I am trying to figure out how to pull data based on column B to individual tabs.

I have the following data



A B C D
Jane Doe | L1 | 20% | High
John Doe | L2 | 15% | Medium
Mike Smith | L1 | 60% | Low
Marie Smith | L4 | 10% | Low


I want to have the first tab/spreadsheet only pull records that have L1 values for column B
In the next tab/spreadsheet I want to pull records that have L2 values in column B etc.

What formula can I write that will pull all L1 records (A.B.C.D) in to Tab 1, then all L2 records (A,B,C,D) into the next tab?
