How can I continue to lookup value from DataTable

Let say I have a DT like below

colA , colB
A, 1
A, 2
A, 3
B, 1
B, 2
A, 4

How can I lookup value “A” from colA and read all 4 rows ?
Do I need to For Each the whole DT row by row ?

Thanks in advance

Filter out the unique from first column and for that you iterate and apply filter


How about FilterDataTable activity?

Got it , many thanks to you all !!
