Reply To: Pasting data into tables: Does it work in CS5 and CS5.5?

Oke, the official answer is:
“The current copy/paste behavior of table cells is as designed and it’s also documented in the ID help where in it says “there should be sufficient number of row/column in the table in which you want to paste the copied content.”
Got this from the Adobe engineers, and indeed the help files states this clearly

So it ONLY works with plain text copy/paste, there it will add rows and columns, NOT if the data on the clipboard is copied from InDesign tables or Excel tables, there it will not work (and, it seems has never worked! One of those ‘memory playing tricks with me’). It depends how the data copied gets on the clipboard if it works or not
