React Data Table Component Demo

React Data Table Component

Creating yet another React table library came out of nescessity while developing a production application for a growing startup. I discovered that while there are some great table libraries already available, most required heavy customization (overriding css and/or forced to use their flavor of ui library), lacked built in sorting or required a commercial license.

If you want to achieve balance with the force and want a simple, sortable, flexible table library, give React Data Table Component a shot. If you want an Excel clone, need to pivot large data sets or want to infinitely scroll millions of rows, then this is not the React table library you are looking for 👋

React Data Table Component is still under Development, though I do not anticpate the API to change much. Here are the initial features available:

• Declarative Configuration
• Sortable (client)
• Selectable Rows
• Expandable Rows
• Themeable via js config
• Data Aware (i.e. easily callback to a parent component get the DataTable state, e.g. selectedRows
• Responsive (via x-scroll/flex)

Roadmap

In order priority:

• Pagination (client/server) - This is currently under development and should be ready soon!
• Built in themes (Material, Boostrap)
• Sortable (server)
• Search (client/server)
• Fixed Headers
• Mobile Responsive
• Accessibility

Installation

npm install react-data-table-component 

// or

yarn add react-data-table-component 

API/Usage

Columns

Nothing new here - we are using an array of object literals and properties to describle the columns:

Property	Type	Required	Example
name	string	no	the display name of our Column e.g. 'Name'
selector	string	yes	the propery in the data set e.g. property1.nested1.nested2.
sortable	bool	no	if the column is sortable
format	func	no	format the selector e.g. row => moment(row.timestamp).format('lll')
cell	func	no	for ultimate control use cell to render your own custom component! e.g row => <h2>{row.title}</h2> Negates format
grow	number	no	flex-grow of the column. the is useful if you want a column to take up more width than its relatives (without having to set widths explicitly). this will be affected by other columns where you have explicityly set widths
width	string	no	give the column a fixed width
minWidth	string	no	give the column a minWidth
maxWidth	string	no	give the column a maxWidth
right	bool	no	right aligns the content in the cell
center	bool	no	center aligns the content in the cell
compact	bool	no	removes any padding in the cell. useful for custom cells icons or buttons
wrap	bool	no	whether the cell content shold be allowed to wrap.
allowOverflow	bool	no	allows content in the cell to overflow. useful for certain menus/layovers
ignoreRowClick	bool	no	implements e.stopPropagation() on a specific Table Cell. This is really useful when you want to trigger some action based on onRowClicked and when you do not want the Table Cell to trigger onRowClicked

DataTable Properties

Property	Type	Required	Default	Description
title	string or component	no		The Title displayed in the Table Header
columns	array	yes	[]	The column configuration
data	array	no	[]	it is highly recommended that your data has a unique identifier (keyField). The default keyField is id. If you need to override this value then see keyField DataTable Properties.
keyField	string	no	'id'	your data should have a unique identifier. By default, React Data Table looks for an id property for each item in your data. You must match keyField to your identifier key, especially if you want to manage row state at a later time. If a unique id is not present, React Data Table will use the row index (not recommended) as the key value
progressPending	bool	no		disables the table and displays a plain text Loading Indicator
progressComponent	component	no		allows you to use your own custom progress component
progressCentered	bool	no		absolutely position and center the progress over the table
selectableRows	bool	no	false	Whether to show selectable checkboxes
selectableRowsComponent	func	no		Override the default checkbox component - must be passed as a function (e.g. Checkbox not <Checkbox />)
selectableRowsComponentProps	object	no		Additional props you want to pass to selectableRowsComponent. See Advanced Selectable Component Options to learn how you can override indeterminate state
expandableRows	bool	no	false	Whether to make a row expandable, if true it requires an expandableRowsComponent. It is highly recommended your data set have a unique identifier defined as the keyField for row expansion to work properly.
expandableRowsComponent	string or component	no		A custom component to display in the expanded row. It will have the data prop composed so that you may access the row data
noDataComponent	string or component	no		A custom component to display when there are no records to display
sortIcon	component	no		Override the default sort icon - the icon must be a font or svg icon and it should be a "downward" icon since animation will be handled by React Data Table
striped	bool	no	false	stripe color the odd rows
highlightOnHover	bool	no	false	if rows are to be highlighted on hover
pointerOnHover	bool	no	false	if rows show a point icon on hover
contextTitle	string	no		override the context menu title
contextActions	array of components	no		add context action as an array of components
onTableUpdate	func	no		callback to access the entire Data Table state ({ allSelected, selectedCount, selectedRows, sortColumn, sortDirection, rows })
onRowClicked	func	no		callback to access the row data,index on row click
clearSelectedRows	bool	no	false	toggling this property clears the selectedRows. If you use redux or react state you need to make sure that you pass a toggled value or the component will not update. See Clearing Selected Rows
defaultSortField	string	no		Setting this ensures the table data is presorted before it renders and the field(selector) is focused
defaultSortAsc	bool	no	true	set this to false if you want the table data to be sorted in DESC order
className	string	no		override the className on the Table wrapper
style	object	no		override the style on the Table wrapper
overflowY	bool	no	false	if a table is responsive, items such as layovers/menus/dropdowns will be clipped on the last row(s) due to to overflow-x-y behavior - setting this value ensures there is invisible space below the table to prevent "clipping". However, if possible, the correct approach is to use menus/layovers/dropdowns that support smart positioning. If used, the table parent element must have a fixed height or height: 100%.
overflowYOffset	string	no	250px	used with overflowY to "fine tune" the offset
responsive	bool	no	true	makes the table horizontally scrollable on smaller screen widths
customTheme	object	no		Override the default theme, by overriding specifc props. Your changes will be merged. See Theming for more information
disabled	bool	no	false	disables the Table section
noHeader	bool	no	false	removes the table header. title, contextTitle and contextActions will be ignored

Advanced Selectable Component Options

Sometimes 3rd party checkbox components have their own way of handling indeterminate state. We don't want React Data Table hardcoded to a specific ui lib or custom component, so instead a "hook" is provided to allow you to pass a function that will be resolved by React Data Table's internal Checkbox for use with indeterminate functionality.

Example Usage:

const { Checkbox } from 'react-md';

...

/* 
  In this example, react-md ui lib determines its indeterminate state via the `uncheckedIcon` property. To override it
  so let's override it. React Data Table is aware if a checkbox is indetermite or not becuase internally we resolve this as 
  `yourfunction(checkboxawareindeterminatestate)`
*/

const handleIndeterminate = isIndeterminate => (isIndeterminate ? <FontIcon>indeterminate_check_box</FontIcon> : <FontIcon>check_box_outline_blank</FontIcon>);

const MyComponent = () => (
  <DataTable
    title="Arnold Movies"
    columns={columns}
    data={data}
    selectableRows
    selectableRowsComponent={Checkbox} // Pass the function only
    selectableRowsComponentProps={{ uncheckedIcon: handleIndeterminate  }}
  />
);

Note This is currently only supported for indeterminate state, but I may expand this out in the future if there is a demand

Basic Table

The following declarative structure creates a sortable table of Arnold movie titles:

import DataTable from 'react-data-table-component`;

const data = [{ title: 'Conan the Barbarian', year: '1982' } ...];
const columns = [
  {
    name: 'Title',
    selector: 'title',
    sortable: true,
  },
  {
    name: 'Year',
    selector: 'year',
    sortable: true,
    right: true,
  },
];

class MyComponent extends Component {
  render { 
    return (
      <DataTable
        title="Arnold Movies"
        columns={columns}
        data={data}
      />
    )
  }
);

Selectable Rows

Let's make our rows selectable so we can access the selected results

...

const handleChange = (state) => {
  // You can use setState or dispatch with something like Redux so we can use the retrieved data
  console.log('Selected Rows: ', state.selectedRows);
};

class MyComponent extends Component {
  render { 
      return (
        <DataTable
          title="Arnold Movies"
          columns={columns}
          data={data}
          selectableRows // add for checkbox selection
          onTableUpdate={handleChange}
        />
    )
  }
);

Clearing Selected Rows

We need some hook to trigger all the selectedRows to clear. If you were building your own table component, you would manage the selected rows state in some parent component, however, in our case, since we to keep row management within React Data Table, a clearSelectedRows prop is provided so you can pass a toggled state.

It will be up to you to make sure you do not pass the same state twice. For example, if you set clearSelectedRows={true} twice, on the second update/trigger, none the rows will not be cleared.

...
// set the initial state
state = { toggledClearRows: false }
...

const handleChange = (state) => {
  // You can use setState or dispatch with something like Redux so we can use the retrieved data
  console.log('Selected Rows: ', state.selectedRows);
};

// Toggle the state so React Table Table changes to `clearSelectedRows` are triggered
const handleClearRows = () => {
  this.setState({ toggledClearRows: !this.state.toggledClearRows})
}

class MyComponent extends Component {
  render { 
    return (
      <DataTable
        title="Arnold Movies"
        columns={columns}
        data={data}
        selectableRows // add for checkbox selection
        onTableUpdate={handleChange}
        clearSelectedRows={this.state.toggledClearRows}
      />
    )
  }
);

Overriding with a 3rd Party Ui Component Library

You don't like those ugly html checkboxes? Let's override them with some react-md sexyiness. While we are at it we will also override the sortIcon:

...
import { Checkbox, FontIcon } from 'react-md';
...

class MyComponent extends Component {
  render { 
    return (
      title="Arnold Movies"
      columns={columns}
      data={data}
      selectableRows
      selectableRowsComponent={Checkbox} // Pass the function only
      selectableRowsComponentProps={{ inkDisabled: true }} // optionally, pass react-md supported props down to our custom checkbox
      sortIcon={<FontIcon>arrow_downward</FontIcon>} // use a material icon for our sort icon
      onTableUpdate={handleChange}
    />
    )
  }
);

Custom Cells

Let's give our Movie list a summary, but in the same cell as Name:

....

const data = [{ title: 'Conan the Barbarian', summary: 'Orphaned boy Conan is enslaved after his village is destroyed...',  year: '1982' } ...];
const columns = [
  {
    name: 'Title',
    sortable: true,
    cell: row => <div><div style={{ fontWeight: bold }}>{row.title}</div>{row.summary}</div>,
  },
  {
    name: 'Year',
    selector: 'year',
    sortable: true,
    right: true,
  },
];

...

class MyComponent extends Component {
  render { 
    return (
      <DataTable
        title="Arnold Movies"
        columns={columns}
        data={data}
        selectableRows
        selectableRowsComponent={Checkbox}
        selectableRowsComponentProps={{ inkDisabled: true }}
        sortIcon={<FontIcon>arrow_downward</FontIcon>}
        onTableUpdate={handleChange}
      />
    )
  }
);

Expandable Rows

Let's make our rows expandable so we can view more details:

...

const data = [{ title: 'Conan the Barbarian', summary: 'Orphaned boy Conan is enslaved after his village is destroyed...',  year: '1982', image: 'http://conan.image.png' } ...];
const columns = [
  {
    name: 'Title',
    sortable: true,
    cell: row => <div><div style={{ fontWeight: 700 }}>{row.title}</div>{row.summary}</div>,
  },
  {
    name: 'Year',
    selector: 'year',
    sortable: true,
    right: true,
  },
];

...

// The row data is composed into your custom expandable component via the data prop
const ExpanableComponent = ({ data }) => <img src={data.image} />;

class MyComponent extends Component {
  render { 
    return (
      <DataTable
        title="Arnold Movies"
        columns={columns}
        data={data}
        selectableRows
        selectableRowsComponent={Checkbox}
        selectableRowsComponentProps={{ inkDisabled: true }}
        sortIcon={<FontIcon>arrow_downward</FontIcon>}
        onTableUpdate={handleChange} 
        expandableRows
        expandableRowsComponent={<ExpanableComponent />}
      />
    )
  }
);

Theming

Under Development

The curent default Theme is very "material". Near term plans are to have 3 built-in prop selectable themes (none, bootstrap, material).

You can override or replace the current theme using the customTheme prop

For Example:

// Override the row default height
const mySweetTheme = {
  rows: {
    height: '64px'
  }
}

class MyComponent extends Component {
  render { 
    return (
      <DataTable
        title="Arnold Movies"
        columns={columns}
        customTheme={mySweetTheme}
      />
    )
  }
);
