How to: Add a Static Column or Row to a Matrix (Report Designer)
In Layout view, right-click the data, or detail, cell of the matrix, and then click Add Column or Add Row. Alternatively, drag a field from the Datasets window onto a populated data cell.
Note: If the Datasets window does not appear, in the View menu, click Datasets.
Repeat step 1 to add multiple static columns or rows to a matrix.
The cell splits to create another static column or row. If you add a column or row by dragging a field, Report Designer displays a dark line on one side of the cell, indicating where the field will be positioned when it is dropped onto the matrix.
Note: When a matrix contains a single static column or row, the cell has no column or row header. When multiple static columns or rows are added to a matrix, a static header is created for each static column or row.
