Java CellEditor

Question

I have a java application, and I use a custom CellEditor class, but now I want to use it only in the cell in column 5 and row 0, and no longer in the entire column 5.

this is part of the code:

table.getColumnModel().getColumn(5).setCellEditor(new ComboBoxCellEditor());

I've already tried all forms of questions for our friend ChatGPT.
