html table span entire width?

There might be a margin style that your table is inheriting. Try setting the margin of the table to 0:

<table border="1" width="100%" ID="Table2" style="margin: 0px;">
  <tr>
    <td>100</td>
  </tr>
</table>

Try (in your <head> section, or existing CSS definitions)...

<style>
  body {
    margin: 0;
    padding: 0;
  }
</style>
