Reply To: vertical strokes in table

Created 3 Paragraph Styles, you may only need two and these are just examples. You can set any text formats you want
Table Header – Bold
Table Body – Normal
Table Footer – Light Italic (Optional, not sure you are using a footer to your table)

Then I create 3 Table Cell Styles
Header – using Table Header para style
Body – using Table Body para style
Footer – using Table Footer para style

Then create the Table Style using the 3 cell styles above.Under the General TAB in the Table Options dialogue box
This is make the Header BOLD, Body NORMAL and Footer ITALIC

Then if you edit the Paragraph Style all the related text will change, or edit a Cell Style and these cells will be affected.
A good way to see if things are working correctly is to edit the style, eg edit the Header paragraph style and make the text colour magenta all the controlled text will change, then just undo or change it back.

Good luck.
