Filter table by lenght of elements in one column.

Hi, I'd like to filter, without using loops, a table by the lenght of an element in a given column. The lenght for my scenario must match 12 in this case.

I tried this, and it was effective, but not sure if it was the most effective one:

filtered_table = myTable(cellfun('length',myTable.thatColumn)==12, :);

I'd like to know if more efficient variations are possible, this is the only one I know unfortunately.

Thanks in advance.
