Hi Omar,
Thanks for the details!
## sometimes I face this issue while trying to change table border:
We can reproduce the reported issue when table contains merged cells. Currently, we are validating and get back to you by May 27,2021.
## In SF DocumentEditor I have to press twice every time to select the border style and border thickness.
Currently, we have provided No border options in dropdown. So, once selected we have to select in border style to apply. We have consider 3*3 matrix UI design. Currently, we are validating how to provide No border , we will check and update you further details by May 27,2021.
Regards,
Suriya M.
