reporting services - SSRS format rows on report -

i have simple report groups rows on person on date. have these 2 groups in grouping pane details group below.

the trouble end person , date appearing @ top of first 2 columns on left, rest of these 2 columns empty space wasting lot of space on left hand side of page.

how can format keep same grouping have person , date appearing on first row other data displayed below. grouping show again single row whenever group changes (which @ moment, loads of dead space on page on left hand side)

i've tried adding 'column group' of person , date, ends report being massive horizontally.

thanks

you put table control inside list control , give them both same datasource , grouping. put person , date fields in list control , position them like. table there display detail , wouldn't have fields person , date.
