Creating a table

To create a table, simply require 'html_table_dsl', include HtmlTableDSL::Table and call the table method, passing in a block that defines the contents of the table:

table do
  header do
    row do
      cell "Header 1"
      cell "Header 2"
    end
  end

  body do
    row do
      cell "Row 1 Cell 1"
      cell "Row 1 Cell 2"
    end

    row do
      cell "Row 2 Cell 1"
      cell "Row 2 Cell 2"
    end
  end
end

This will output the following HTML code in string format:

<table>
  <thead>
    <tr>
      <th>Header 1</th>
      <th>Header 2</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Row 1 Cell 1</td>
      <td>Row 1 Cell 2</td>
    </tr>
    <tr>
      <td>Row 2 Cell 1</td>
      <td>Row 2 Cell 2</td>
    </tr>
  </tbody>
</table>

Adding attributes and styles

You can also add attributes and styles to your table, headers, rows, and cells by passing in a hash:

table class: "my-table", style: "border: 1px solid black;", width: "800px" do
  header do
    row do
      cell "Header 1", class: "header-cell", style: "text-align: center;"
      cell "Header 2", class: "header-cell", style: "text-align: center;"
    end
  end

  body do
    row class: "even-row", style: "background-color: lightgrey"  do
      cell "Row 1 Cell 1", class: "cell"
      cell "Row 1 Cell 2", class: "cell"
    end

    row do
      cell "Row 2 Cell 1", class: "cell"
      cell "Row 2 Cell 2", class: "cell"
    end
  end
end
