Report Formatting

Hi,
I have to generate a report in this format
-----------------------------------------------------------------------------
Id NO date1 date2 date3 date4 defination
-----------------------------------------------------------------------------
1 xxx xxx xxx xxx ABC
2 xx yy yy LMN
3 22 33 xxx fff HIF
3 22 33 xxx fff TEST
3 22 33 xxx fff BEST
3 22 33 xxx fff TRUST




The problem is for the field Id No where
the fields---------------- Id No, date1 ,date2,date3,date4 are same and only defination is differrent
they do not want me
to repeat the same data but shown it once and display all the different defination like below


-----------------------------------------------------------------------------
Id NO date1 date2 date3 date4 defination
-----------------------------------------------------------------------------
1 xxx xxx xxx xxx ABC
2 xx yy yy LMN
3 22 33 xxx fff HIF






TEST
BEST
TRUST

I tried doing grouping by IdNO and show defination in seperate detail line,it gives
the field defination in the next line like below, which the end users dont want

Id NO date1 date2 date3 date4 defination
-----------------------------------------------------------------------------
1 xxx xxx xxx xxx






ABC
2 xx yy yy






LMN
3 22 33 xxx fff






HIF

Is there any other solution??

Thanks
