Tables in Description are Buggy

Tables within a description seem to be buggy. For example, if I try to copy/paste cells (similar to a spreadsheet), when you paste them, it doesn't always paste the cells in a logical way. They'll paste into the table almost at random. 

Also, I've noticed that when I insert a new row or column, sometimes recently inputted cells will get cleared out (not immediately...but within a few minutes I'll come back to the table and find that my work has disappeared and isn't available in the history feature.)
