Create a hairline border around your tables for http documents.
This example requires R5:
To create a hairline border containing the color of your choice, start by creating a single column, single row table -- setting borders to zero and the cell color to the color of your choice.
Then, inside that table create your actual table, setting all borders to zero.
Now, click back into the first table and bring up the properties dialog. Click on the HTML options tab (the "@" -- furthest to the right) and add the following code in the [TABLE HTML TAGS] [OTHER] input field: CELLPADDING=1
Preview the document and you'll see a table with a hairline border.
Alternately: You can add the hairline border color to all columns in your table by selecting the nested table (the second one you created) and add the following code in the [TABLE HTML TAGS] [OTHER] input field: CELLSPACING=1.
