SSRS Report Logic

I have got data in a temp table in AX 2012 for a ssrs report.

I designed two tables adjacent to each other in SSRS Designer for my report.

Now i need to insert data into the first table from 1 to 10 records and second table with the continuation from 11 to 20 records.

if there are more than 20 records. i need to insert the records from 21 to 30 again in first table and 31 to 40 in second table and so on.

how could i do this, through logic or expressions??

Thanks in Advance.
