Verify input in jTable except for head row

Hi.

I have a jTable with doubles or integers in every cell except for the top row, which can be user changed too, but can contain anything.
How can I validate user input for it being a numeric value?

I know there is an approach like this:
table.getColumnModel().getColumn(x).setCellEditor(CustomEditor())

but if I use this on every column the top row will be restricted to.
Maybe there there is a way for validating rows instead of columns?

Thank you, all help appreciated!

Override the table method getCellEditor(...). If the row is 0, return a default editor otherwise return super.getCellEditor()
