Let's say I have a table cell with fixed width and height.... and I have data that exceeds the cell's fixed dimensions...
<td width="500" height="300">lots of data that exceeds the dimensions</td>
The easiest thing would be to add a 500 x 300 div and give it overflow: auto
<td width="500" height="300">
<div style="width: 500px; height: 300px; overflow: auto">
lots of data that exceeds the dimensions
</div>
</td>
