The Format Assistant will open with the Layout tab selected. If the layout you are using is gray, then it is a factory layout and is locked. You must duplicate it so that you can edit it. Do so, and then click on the Fields tab as shown in the attached screenshot.
This is where it feels like you are in the dark ages. To modify your data record columns, you want the Record selector as shown and you'll see how many columns of data will be displayed. There is NO linkage between this number 8 in my screenshot and the number of checkboxes selected earlier for data to display!! Just the way it is.
Change the column number for the 'Field to Edit" as I have ... I'm showing "2"... and you'll see the Text Field value that will be displayed for that column.
In my screenshot you see #Value[2] which means absolutely nothing to you or me! The parameter name is not displayed!
Below that is an Insert button and a data field selection dropdown. Depending on what data field you select (recognizable NAME), one of these #value[number] fields will be inserted into the Text Field and match up with the field when the list is generated. Totally insane by today's software standards and expectations, but that's just what it is.
So... you want to delete a column. If it's column 5, then we don't need to figure out the #value[] stuff ... just delete column 5, right? Wrong... there is no "delete column" or "delete field" action in this dialog. You can only TRIM the columns back and set up subsequent columns manually... as far as I can see.
So, if you want to delete column 5, you would change Columns in my screenshot from 8 to 4. Then you would have to re-insert the fields for columns 6, 7 and 8 as the new 5, 6 and 7.
If there is a delete button that I don't see... or some way other than editing in an external text editor to delete one column... maybe someone else will post a solution.
