How to access table properties to change border size?

How to access table properties to change border size in Scrivener 3 for Windows?
With thanks

I add table to format toolbar via View>customize toolbars then is always there.
Once there click on icon and will create a table for you with properties box available. If leave this view, then click INSIDE the table with mouse and then right click will see table at top of right click menu and clicking this will bring up table property box, but can also add or delete rows via right click as well. I hope that helps.

Thank you GoalieDad, you scored well! All the tutorials I found were for Mac and had borders on the right-click menu, missing from this version.
With much gratitude, and a smile …

glad to help, I glad that will work for you. Note as type table automatically expands to accomadate the text
