that doesn't sound right because anything inside the <td></td> tag would be treated as text *unless* the built in parsers couldn't figure out what to do with them (or a custom parser was defined)
so the columns could be like <td>A</td><td><input type="checkbox" checked="checked" /></td> <td>B</td><td><input type="checkbox" /></td> <td>C</td><td><input type="checkbox" /></td> <td>D</td><td><input type="checkbox" checked="checked" /></td> <td>E</td><td><input type="checkbox" checked="checked" /></td> and it would sort <td>B</td><td><input type="checkbox" /></td> <td>C</td><td><input type="checkbox" /></td> <td>A</td><td><input type="checkbox" checked="checked" /></td> <td>D</td><td><input type="checkbox" checked="checked" /></td> <td>E</td><td><input type="checkbox" checked="checked" /></td> because "<input type="checkbox" />" comes before "<input type="checkbox" checked="checked" />"
