Matrix heading formatting - Merge

Hi roger360,

Thank you for reaching out in Microsoft Community Forum.

To clarify, in Step 1, you should create the Calculation Group with a calculation item named Issue Category, not System Issue. This will serve as the custom header in your Matrix table.

Please follow below steps to verify,

1.Create a Calculation Group using Tabular Editor with a calculation item named Issue Category (this will act as the group header).

2.Add the Calculation Group as a column in the matrix table to simulate the desired group header.

3.Adjust the formatting to align the header height with the other columns.

Please continue using Microsoft community forum.
