# Add or remove borders from all tables in a document [closed]

I have a LaTeX document with several tables. All these tables do not have borders. I would like to add borders to all these tables. Adding borders one by one to each table is a daunting task. Is there a simpler way to add (and remove) borders to all the tables in a LaTeX document?

• why you should add borders? tables without border are more beautiful :-). i'm afraid, that this change you should do manually, maybe with help of editor (difficult to say since i don't know how the tables looks) – Zarko Apr 5 '18 at 18:33
• @Zarko Personally, I also prefer tables without borders. That's the reason I made all the tables without borders in the first place. But this is my thesis document and I'm in a position where I have to add borders to all the tables. – BEFL Apr 5 '18 at 19:21
• With a regex search and replace feature (available in many text editors) you can probably do this fast: replace \begin{tabular}{ until the next } with \begin{tabular}{| and |}, replace \end{tabular} with \hline\end{tabular}, etc.. (or adjust accordingly for booktabs, longtable, ...) – Marijn Apr 5 '18 at 20:37
