What inspired this wish list request?
Prior to JMP19, column names could be changed by pasting text into the Columns window in a Data Table. This was incredibly useful for quickly and easily changing column names. This functionality is now gone in JMP19.

What is the improvement you would like to see?
Please restore the ability to change column names by pasting text into the Columns window.
Why is this idea important?
Changing column names is a regular task in data formatting.
