Scrivener frozen when adjusting the border of a table?

My project is a large one, I’ve tables in different sections. But the app got frozen while I was adjusting the border location of a particular table (all other tables are no problem).

I also tried creating a new project, then no such problem.
Do you have any idea about this issue? Thank you!

Some more information to add: I think I pasted the problematic table from some webpage. I did another experiement: I just copied the problematic table and pasted in a new project. Then I could freely resize the column width by adjusting the location of the border without problem. Finally I pasted the table back in my huge project, then the issue disappeared! It may be a workaround if you encounter the similar issue.
