Table Plug-in that allows easy table width/row height?

I need to 2 columns of 17 rows and the columns need to be 200px wide, or perhaps left column 200 and right column 300.

Is there a table plug-in that includes the ability to this without resorting to CustomCSS? I do not want to have the same table widths on every page, etc. I will want to have many different tables with many different column widths that are static widths and occasionally a static row height.

I found one query on here that said just select edit as html, but then the block gets an error when I put in <td width=”300″> for one of the columns and asks me to try to recover the block, which ended up destroying the entire thing. So now I need to start over.
