Check if rows are on data table by using only first column

Hopefully this will be a simple one.
I am trying to determine if there are any rows in a datatable but because of certain formulas, it will always return a yes.

What I want to do is just check the first column and if there are are entries in there, then return a yes value, if not, return a no.

I know can check if the datatable has rows overall by using
dt.Rows.Count < 1
but how do I configure this to only check the first column rathe than the full row

This should work

DT.Select("[ColumnName] is not null").Count > 0
