Data-auto filter- how to choose just one column?

Hello!
If I have a table in calc, and want to use data- filter- autofilter
I cant avoid that the function spreeds to ALL COMUNMS.
Please, what to do if I wnt it in just one column?
Many thanks!

Just select this column BEFORE choosing Data-Filter-Autofilter

Select the column, or select first the range to filter with their head.
