two chart inside table not 50-50%

firstly, Great Plugin, thanks.

i tried many times but failed, for more than one chart in the same line.
let say there should be two chart alongside each other. The first one is bigger and the other one is narrower, how could I solve this?
below is the simple html i used in text editor

<table style="width: 100%;">
<tbody>
<tr>
<td>[visualizer id="517"]</td>
<td>[visualizer id="518"]</td>
</tr>
</tbody>
</table>

(value using the columns default as an example)

thanks very much for the help
