Spotfire HTML formatting (Horizontal) for filters in textarea

<table>

<tbody>

<tr>

    <td valign="top"><p align="left">(Write heading 1 here)</p></td>

    <td valign="top"><p align="left">(Write heading 2 here)</p></td>

</tr>

<tr>

    <td> (Add filter control 1 here)</td>

   <td> (Add filter control 2 here)</td>

</tr> 

</tbody>

</table>

Few suggestions:

Repeat section in  <td></td> (orange marked) for more filters

Change valign = middle / bottom as required.

Write <table bgcolor=”red”> to give red color to canvas

More advance is there and you can build very nice webpage  with css and jquey.
