What inspired this wish list request? JMP18 had the feature of displaying the number of rows and columns in the join preview table, which is often used to make sure the resulting table is joined correctly. JMP19 does not have this.
What is the improvement you would like to see? Bring back the display of the number of rows and columns in a joined table in JMP19.
Why is this idea important? The value case for me is in the ease of use. Not having the number of rows and columns visible requires either scrolling to the bottom or right of what could be a very large table, or generating the table to check the dimensions there. I was not personally bothered or distracted by having the values there and would love to see them put back.
