Well, instead of just "try this" I will attempt to explain a little
bit.  Tables in HTML can never have rounded corners they are rectangle
- End of Story.  The only way, as the link explains, to achieve a
"rounded corner" look to your tables is to make images of corners, and
put them in the outside edges of your tables.  So put your corner
images where the x's are below.  This is an example using a 3x3 table.

-------------------
| x |         | x |
-------------------
|   |         |   |
|   | content |   |
|   |         |   |
-------------------
| x |         | x |
-------------------

Then, just set the backgrounds of the other border cells to the same
color as your corner images.

In addition to what I said before, this is an excellent visual
tutorial without all the code jargon.
