You have a mess of nested tables there. My suggestion would be to rework the design so that you are using DIVs for placement, and tables only where the actual statistical data is.

Anyway, by setting the table widths for the charts to 50% instead of by pixel, and setting your containing <tr> valign=top, you can achieve this:

But you need to look into fixing the layout, as tables are not a good method to get the effect you’re going for.

A couple things.

First, your surrounding tables have varying widths (from 65% to 100%). I would suggest setting them all to 100%:

Next, the tables within them, set the TD values to 50% width, instead of specifying to the pixel:

Third, set your TR vertical align to TOP for the row that is holding the cells:

And you will end up with this:
