Default setup

Tables need to have the class matrix to look like this. All tables need to be properly constructed with thead and tbody. Odd and even rows have alternating colors.

Column header Column header
Row header Odd row Odd row
Row header Even row Even row
Row header Odd row Odd row 
    <table class="matrix">
      <thead>
        <tr>
          <th></th>
          <th>Column header</th>
          <th>Column header</th>
        </tr>
      </thead>
      <tbody>
        <tr>
          <th>Row header</th>
          <td>Odd row</td>
          <td>Odd row</td>
        </tr>
        <tr>
          <th>Row header</th>
          <td>Even row</td>
          <td>Even row</td>
        </tr>
        <tr>
          <th>Row header</th>
          <td>Odd row</td>
          <td>Odd row</td>
        </tr>
      </tbody>
    </table>

Numeric data

If your table contains numeric data you might want to align them on the right side. You can do this either per cell td.numeric, per row tr.numeric or per column col.numeric.

Column header Column with class numeric
Row with class numeric 1234 1234
Cells with class numeric 1234 1234 
    <table class="matrix">
      <colgroup>
        <col>
        <col>
        <col class="numeric">
      </colgroup>
      <thead>
        <tr>
          <th></th>
          <th>Column header</th>
          <th>Column with class <i>numeric</i></th>
        </tr>
      </thead>
      <tbody>
        <tr class="numeric">
          <th>Row with class <i>numeric</i></th>
          <td>1234</td>
          <td>1234</td>
        </tr>
        <tr>
          <th>Cells with class <i>numeric</i></th>
          <td class="numeric">1234</td>
          <td class="numeric">1234</td>
        </tr>
      </tbody>
    </table>
