This is a macro that automatically generates an HTML table from a list of lists.

macro ( 'AutoTable', lambda data, header=False: (
    assign ( 'alts', [ 'even', 'odd' ] ),
    data and (
        T.table ( class_='autotable' ) [
            header and (
                T.thead [ [ T.th [ _col ] for _col in data [ 0 ] ] ]
            ),
            T.tbody [
                [ T.tr ( class_='row-%s' % alts [ _rx % 2 ] ) [
                    [ T.td ( class_='col-%s' % alts [ _cx % 2 ] ) [ _col ]
                      for _cx, _col in enumerate ( _row ) ]
                ] for _rx, _row in enumerate ( data [ int ( header ): ] ) ]
            ]
        ]
    )
) )

Assuming you have a list of lists like this:

data = [
    [ 'A', 'B', 'C', 'D' ],
    range ( 0, 4 ),
    range ( 4, 8 ),
    range ( 8, 12 )
]

and a template like this:

html [
    head [ title [ 'AutoTable Demo' ] ],
    body [
        AutoTable ( data, header=True )
    ]
]

AutoTable would generate the following HTML:

<html>
  <head><title>AutoTable Demo</title></head>
  <body>
    <table class="autotable">
      <thead>
        <th>A</th><th>B</th><th>C</th><th>D</th>
      </thead>
      <tbody>
        <tr class="row-even">
          <td class="col-even">0</td>
          <td class="col-odd">1</td>
          <td class="col-even">2</td>
          <td class="col-odd">3</td>
        </tr>
        <tr class="row-odd">
          <td class="col-even">4</td>
          <td class="col-odd">5</td>
          <td class="col-even">6</td>
          <td class="col-odd">7</td>
        </tr>
        <tr class="row-even">
          <td class="col-even">8</td>
          <td class="col-odd">9</td>
          <td class="col-even">10</td>
          <td class="col-odd">11</td>
        </tr>
      </tbody>
    </table>
  </body>
</html>
