LO-calc: How to change border thickness in multiple worksheets

I have a LibreOffice Calc file with multiple worksheets and would like to change the thickness of the borders of all the cells in all the sheets with one action.


Select the worksheets tabs you want (add or remove with Ctrl+click). Select range, apply borders, and DEselect worksheets tabs before continue working (if all worksheets tabs are selected, a change of worksheet it’s enough; if not, change to a non selected worksheet).
