slate-edit-table
![Linux Build Status](https://travis-ci.org/GitbookIO/slate-edit-table.png?branch=master)
A Slate plugin to handle table edition.
Demo: gitbookio.github.io/slate-edit-table/
Install
npm install slate-edit-table
Features
- Pressing Up/Down moves the cursor to the row above/below
- Pressing Enter inserts a new row
- Pressing Cmd+Enter (Ctrl+Enter on Windows/Linux) exits the table, into a new default block
- Pressing Tab moves the cursor to next cell
- Pressing Shift+Tab moves the cursor to previous cell
All these default features are configurable.
Copy/Paste behavior
Here are how different cases of copy-paste are handled by the plugin:
- Copying the content of a single cell into another cell → The content of the first cell is pasted inside the second cell
- Copying the content of a single cell outside the table → Just the content of the cell is pasted (not the table)
- Copying some content into a cell → The content is inserted inside the cell
- Copying multiple cells somewhere else inside the table → The copied fragment of table is patched at the given position, overwritting cells and adding rows and columns if necessary.
- Copying multiple cells outside the table → A new table is pasted, containing the copied cells.
Simple Usage
import EditTable from 'slate-edit-table';
const tablePlugin = EditTable();
const plugins = [tablePlugin];
Data structure
Here is what your Slate document containing tables should look like:
<value>
<document>
<paragraph>Some text</paragraph>
<table>
<table_row>
<table_cell>
<paragraph>Any block can goes into cells</paragraph>
</table_cell>
<table_cell>
<image isVoid src="image.png" />
</table_cell>
</table_row>
<table_row>
<table_cell>
<paragraph>Second row</paragraph>
</table_cell>
<table_cell>
<paragraph>Second row</paragraph>
</table_cell>
</table_row>
</table>
</document>
</value>
Options
Option object you can pass to the plugin.
[typeTable: string]
— type for table[typeRow: string]
— type for the rows.[typeCell: string]
— type for the cells.[typeContent: string]
— default type for blocks in cells. Also used as default type for blocks created when exiting the table with Mod+Enter.
EditTable
EditTable(options: Options) => Instance
Constructs an instance of the table plugin, for the given options. You can then add this instance to the list of plugins passed to Slate.
Once you have constructed an instance of the plugin, you get access to utilities and changes through pluginInstance.utils
and pluginInstance.changes
.
Utils
utils.isSelectionInTable
isSelectionInTable(value: Slate.Value) => boolean
Return true if selection is inside a table cell.
utils.isSelectionOutOfTable
isSelectionOutOfTable(value: Slate.Value) => boolean
Return true if selection starts and ends both outside any table. (Notice: it is NOT the opposite value of isSelectionInTable
)
utils.getPosition
getPosition(value: Slate.Value) => TablePosition
Returns the position of the cursor in a table (and all related infos).
utils.getPositionByKey
getPositionByKey(tableAncestor: Node, key: string) => TablePosition
Returns the position of a particular node in a table (and all related infos).
utils.createTable
createTable(
columns: number,
rows: number,
getCellContent?: (row: number, column: number) => Node[]
): Block
Returns a table. The content can be filled with the given getCellContent
generator.
utils.createRow
createRow(
columns: number,
getCellContent?: (column: number) => Node[]
): Block
Returns a row. The content can be filled with the given getCellContent
generator.
utils.createCell
createCell(opts: Options, nodes?: Node[]): Block
Returns a cell. The content defaults to an empty typeContent
block.
Changes
changes.insertTable
insertTable(change: Change, columns: ?number, rows: ?number) => Change
Insert a new empty table.
changes.insertRow
insertRow(
opts: Options,
change: Change,
at?: number,
getRow?: (columns: number) => Block
): Change
Insert a new row after the current one or at the specific index (at
).
changes.insertColumn
insertColumn(
opts: Options,
change: Change,
at?: number,
getCell?: (column: number, row: number) => Block
): Change
Insert a new column after the current one or at the specific index (at
).
changes.removeTable
removeTable(change: Change) => Change
Remove current table.
changes.removeTableByKey
removeTableByKey(change: Change, key: string) => Change
Remove the table containing the given key.
changes.removeRow
removeRow(change: Change, at: ?number) => Change
Remove current row or the one at a specific index (at
).
changes.removeRowByKey
removeRowByKey(change: Change, key: string) => Change
Remove the row containing the given key.
changes.removeColumn
removeColumn(change: Change, at: ?number) => Change
Remove current column or the one at a specific index (at
).
changes.removeColumnByKey
removeColumnByKey(change: Change, key: string) => Change
Remove the column containing the given key.
changes.moveSelection
moveSelection(change: Change, column: number, row: number) => Change
Move the selection to a specific position in the table.
changes.moveSelectionBy
moveSelectionBy(change: Change, column: number, row: number) => Change
Move the selection by the given amount of columns and rows.
TablePosition
An instance of TablePosition
represents a position within a table (row and column).
You can get your current position in a table by using plugin.utils.getPosition(value)
.
position.getWidth() => number
Returns the number of columns in the current table.
position.getHeight() => number
Returns the number of rows in the current table.
position.getRowIndex() => number
Returns the index of the current row in the table.
position.getColumnIndex() => number
Return the index of the current column in the table.
position.isFirstCell() => boolean
True if on first row and first column of the table
position.isLastCell() => boolean
True if on last row and last column of the table
position.isFirstRow() => boolean
True if on first row
position.isLastRow() => boolean
True if on last row
position.isFirstColumn() => boolean
True if on first column
position.isLastColumn() => boolean
True if on last column
