Hi community i have one Calculated field and i want to format its cell color. We have tried using placeholder but its not working, we have tried extension but thing is its structure gets changed if formatting is applied.

Eg: we have week ending date in col shelf as per client requirement on using extension we are getting formatting for expected column but sturucture of table is changed.this is excel sheet of client and formatting for % diff column.following is workbook structure we have created. what shall we do so that only rolling avg vs prev roll avg column is formatted

On using Tableau table extension we are getting following result on sample dataset where basic Order date structure is changed to rows from columns.

Any guidance on how this can be tackled.
