How to implement this design in SSRS

Answer 1

Assuming you cannot change your stored proc (if you can then you can do this work in there directly).

DECLARE @RowWidth int = 5
CREATE TABLE #t (GroupLabel CHAR(1), SeatLabel int)

INSERT INTO #t EXEC myStoredProc

SELECT 
        GroupLabel, SeatLabel
        , CEILING((SeatLabel -1) / @RowWidth)  AS SeatRow
        , (SeatLabel - 1) % @RowWidth as colGrp
    FROM #t

If your stored proc produced 20 results, A 1-10 and B-10 then the results would be as follows.

Add a mtrix control and then group by GroupLabel and SeatRow as row groups and then add a column group on colGrp.

The final report design looks something like this (the expression is simply GroupLabel and SeatLabel concatenated. ( =Fields!GroupLabel.Value & Fields!SeatLabel.Value )

And the final output looks like this

It's not 100% but with a bit of formatting it should be close enough.
