Table borders in PowerPoint are usually thin, possessing just 1pt. weight (thickness) — that’s not as thin as a human hair, but still quite thin. Most of the times you may not need to change that value since you can clearly see the border, and it is not too eye-catching. However, if you want to change the weight of table borders, it can be done in the same way as you would change their color or line style attributes. Your table borders can be of any weight starting from a miniscule 0.25 pt. to a haughty 6pt., and no higher. Even 6 pt. is very thick for a table border, so be careful just to make sure that your table borders don’t look too blocky or distracting.
