Unable to wrap field headers as desired

Jake5

Hello - I have the attached workflow where I'm trying to get the table's field headers to wrap and appear as shown in the attached screen capture...basically where the parenthesis for each header wraps to the next line.  I had research this earlier and found the formula and Dyanamic Rename tools to try and accomplish this.  However, when adding the formula in, the Report Text tool indicates the Table having a bad field type.  Any suggestions on what is needed in order to get this to work?

One way all columns are text is to make a header across the lines. It is not possible to merge or reduce the size of the report to fit all columns with breaks.
And this feature you were using does not effect a line break.
