Are the lists of columns you are referring to, actual JMP LIsts structures from JSL?
Have you actually grouped the columns into JMP column groups?
Is the issue that you are "Hiding" the lcolumns, so you can only actually see a specific set of columns?
I would like to see more specifics on what you are attempting to do.
I suggest you look into the Column Grouping. It would allow you to handle what seems to be an overwhelming number of columns. The example below is based upong the Semiconductor Capability data table from the JMP Sample tables. Please note, by default it only displays the group title in the filters, unless you exspand the list by clicking on the triangle to the left of the group name.
