table.lib

This is a versatile and user-friendly C# (.NET 8) table library that can quickly render any List<T> or Dictionary<TV, T> into a visually appealing markdown, CSV, HTML, SpecFlow, SQL-insert, or console table format, while providing flexibility for other formats as well. In addition, it also supports dynamic returns from Dapper as IEnumerable<IDictionary<string, object>> via DBTable object. Whether you need to format data for documentation, testing, or display purposes, this library makes it easy to do so in a variety of formats, with just a few lines of code.

table.lib

Simple c# (.NET 6) table library that renders any List<T> or Dictionary<TV, T> into a nicely formatted markdown, csv, html, specflow, sql-insert or console table, allowing for extra formats. It also supports dynamic returns from Dapper as IEnumerable<IDictionary<string, object>> via DBTable object.

Installation

dotnet add package table.lib --version 1.8.1

Markdown format in the console output

To make it easier to share, table.lib outputs the console output as markdown friendly. Note that there is a specific markdown output so the text justification can happen as per markdown specification.

Table<TestClass>.Add(list).ToConsole();

| Field1 | Field2               | Field3        | Field4 | Field5      | Field6 |
| ------ | -------------------- | ------------- | ------ | ----------- | ------ |
| 321121 | Hi 312321            | 2,121.32      | True   | 01-Jan-1970 | 34.43  |

Considerations:

  • Any CRLF will be automatically transformed into a space for an easy representation of the output

Dynamic Fields

If the List contains another collection of , the library is able to scan those and build the resultant dataset giving them a column name called DynamicN:

var test = new List<IEnumerable<string>>
{
    new List<string>() {"AAA", "BBB", "CCC"},
    new List<string>() {"AAA", "BBB", "CCC"},
    new List<string>() {"AAA", "BBB", "CCC"},
    new List<string>() {"AAA", "BBB", "CCC"}
};

Table<IEnumerable<string>>.Add(test).ToConsole();

| Capacity | Count | Dynamic0 | Dynamic1 | Dynamic2 |
| -------- | ----- | -------- | -------- | -------- |
| 4        | 3     | AAA      | BBB      | CCC      |
| 4        | 3     | AAA      | BBB      | CCC      |
| 4        | 3     | AAA      | BBB      | CCC      |
| 4        | 3     | AAA      | BBB      | CCC      |

Column Name change

If the name of the column is not of your liking, you can change it via OverrideColumnsNames and provide your preferred name. Note that this will also alter the column width to allow for more room if the new name is larger than the previous one.

Table<IEnumerable<string>>.Add(test)
    .OverrideColumnsNames(new Dictionary<string, string> {{"Dynamic0","ColumnA"}})
    .ToConsole();

| Capacity | Count | ColumnA  | Dynamic1 | Dynamic2 |
| -------- | ----- | -------- | -------- | -------- |
| 4        | 3     | AAA      | BBB      | CCC      |
| 4        | 3     | AAA      | BBB      | CCC      |
| 4        | 3     | AAA      | BBB      | CCC      |
| 4        | 3     | AAA      | BBB      | CCC      |

Column filtering

You don't want to show all the columns? Easy, just use the FilterColumns property and define the action to perform FilterAction.Include or FilterAction.Exclude:

By default it will use the FilterAction.Exclude functionality:

Table<IEnumerable<string>>.Add(test)
    .OverrideColumnsNames(new Dictionary<string, string> { { "Dynamic0", "ColumnA" } })
    .FilterColumns(new []{ "Capacity", "Count" })
    .ToConsole();

| ColumnA  | Dynamic1 | Dynamic2 |
| -------- | -------- | -------- |
| AAA      | BBB      | CCC      |
| AAA      | BBB      | CCC      |
| AAA      | BBB      | CCC      |
| AAA      | BBB      | CCC      |

Table<IEnumerable<string>>.Add(test)
    .OverrideColumnsNames(new Dictionary<string, string> { { "Dynamic0", "ColumnA" } })
    .FilterColumns(new []{ "Dynamic0" }, FilterActions.Include)
    .ToConsole();

| Dynamic0 |
| -------- |
| AAA      |
| AAA      |
| AAA      |
| AAA      |

Row Highlighter

With a simple operation, we can now highlight the entire content of the table using the code below:

Table<IEnumerable<string>>.Add(GetStringMatrix())
    .FilterColumns(new[] { "Dynamic0", "Dynamic1" }, FilterAction.Include)
    .HighlightRows(ConsoleColor.Red, ConsoleColor.White)
    .ToConsole();

**Note that this option will highlight all the rows

Field Highlighter

You need more control over the field you want to highlight? then use the highlight operator:

Table<TestClass>.Add(GetSampleOutput())
    .HighlightValue(new HighlightOperator
        {Field = "Field3", Type = HighlightType.Decimal, DecimalValue = 2121.32m})
    .ToConsole();

**Note that this option will highlight one specific cell and it will use two colors, one for = and one for <>

Column Justification

You need one of the columns, right aligned or centered? Use the column justification option.

Table<IEnumerable<string>>.Add(test)
    .OverrideColumnsNames(new Dictionary<string, string>
    {
        { "Dynamic0", "A" },
        { "Dynamic1", "B" },
        { "Dynamic2", "C" }
    })
    .FilterOutColumns(new[] { "Capacity", "Count" })
    .ColumnContentTextJustification(new Dictionary<string, TextJustification>
    {
        { "Dynamic0", TextJustification.Right }, 
        { "Dynamic1", TextJustification.Centered }
    })
    .ToConsole();

Note that this will only affect markdown, console and html outputs and only their data. Columns labels will remain left aligned.

|    A     |    B     |    C     |
| -------- | -------- | -------- |
|      AAA |   BBB    | CCC      |
|      AAA |   BBB    | CCC      |
|      AAA |   BBB    | CCC      |
|      AAA |   BBB    | CCC      |

HTML Output

Transform your output into a nicely formatted HTML table

Table<IEnumerable<string>>.Add(test)
    .OverrideColumnsNames(new Dictionary<string, string> { { "Dynamic0", "ColumnA" } })
    .FilterColumns(new []{ "Capacity", "Count" })
    .ToHtml(@"C:\temp\test.html");

Table<TestClass>.Add(list)
    .ToHtml(@"C:\temp\test-list.html");

CSV Output

Trasform your output into a nicely formatted CSV file

Table<TestClass>.Add(list)
    .ToCsv(@"C:\temp\test-list.csv");

The format of the file can be seen here:

Field1,Field2,Field3,Field4,Field5,Field6
321121,Hi 312321,"2,121.32",True,01-Jan-1970,34.43

13,Hi very long text,"21,111,121.32",True,01-Jan-1970,34.43
13,"Hi very, long text","21,111,121.32",True,01-Jan-1970,34.43
13,"Hi ""very"" long
 text","21,111,121.32",True,01-Jan-1970,34.43

Note that we use the CSV standard when processing CRLF, " or , characters surrouding the value with double quotes.

SpecFlow output

Do you deal a lot with SpecFlow tests and want to have something that will generate the output nicely from Dapper? Here it's a simple output:

    var s = Table<TestClass>.Add(GetSampleOutput()).ToSpecFlowString();
    Console.Write(s);

and it becomes:

| Id | SenderId | SenderUsername | RecipientId | RecipientUsername | Content | DateRead |     MessageSent     | SenderDeleted | RecipientDeleted |
| 1  | 5        | lilly          | 8           | ruiz              | hi      |          | 08/02/2021 10:07:07 | False         | False            |
| 2  | 5        | lilly          | 8           | ruiz              | hello   |          | 21/02/2021 20:40:08 | False         | False            |

ToString output

Do you want to render the table somewhere else? Then just use the ToString method and bring the table anywhere with you. This will only produce the console output and return it as string.

ToSqlInsertString

This format will allow you to output a sql string from a specific object like below:

var s = Table<TestClass>.Add(Samples.GetSampleOutput()).ToSqlInsertString();
            var lines = s.Split(Environment.NewLine);
            Assert.Multiple(() =>
            {
                Assert.That(lines[0], Is.EqualTo("INSERT INTO TestClass (Field1,Field2,Field3,Field4,Field5,Field6) VALUES (321121,'Hi 312321',2121.32,1,'1970-01-01',34.43);"));
                Assert.That(lines[1], Is.EqualTo("INSERT INTO TestClass (Field1,Field2,Field3,Field4,Field5,Field6) VALUES (32321,'Hi long text',21111111.32,1,'1970-01-01',34.43);"));
                Assert.That(lines[2], Is.EqualTo("INSERT INTO TestClass (Field1,Field2,Field3,Field4,Field5,Field6) VALUES (321,'Hi longer text',2121.32,1,'1970-01-01',34.43);"));
                Assert.That(lines[3], Is.EqualTo("INSERT INTO TestClass (Field1,Field2,Field3,Field4,Field5,Field6) VALUES (13,'Hi very long text',21111121.32,1,'1970-01-01',34.43);"));
            });

Known Issues

  • Simple dictionaries Dictionary<int, string> will not work. The second argument needs to be a class.
