[libreoffice-users] Add a 'Sort' button to the tops of columns?

There has got to be a reasonably easy way to do this (by 'reasonable', I
mean a way that doesn't require me to become a programmer)...

How do I add a 'Sort' button to the tops of columns, so that I can
easily sort the data in a spreadsheet on different columns simply by
clicking the button in the column header?

I've seen these in spreadsheets I get from Excel users all the time, but
for the life of me can't figure out how to do this in Calc.
