SSRS Grouping question?

Hi everyone,

I am new to the SSRS and Have data like to be present as below, they are all from the same dataset, just like to group 2 columns, that is [WrkCrtId, Name] show on top of them.

I’ve tried some ways to do this but still fail, I was wondering if any one can help?

many thanks.

p.s. image below shows 2 groups (B3 and B7)
