How would you make a 5px separation between 2 tables, if theyre already both in a bigger table? Is there some margin command?

It depends on how your tables are laid out .. are they side by side or one above the other? Are they in separate td cells or are they together?

You should be able to accomplish proper spacing with the attributes style="padding-right: 5px" or style="margin-bottom: 5px", for example, depending on which side of which element you're adjusting the spacing and whether you're making adjustments to the containing td elements or to the embedded tables themselves. You may also need to remove opposing spacing or margin with similar attributes.

use a style sheet and add a 5px margin to the table

thanks for the help guys it worked out perfectly.
