Filter jTable by ImageIcon column

Question

I have a JTable with 3 columns and the second column has ImageIcon s. I want to filter that column only by the name of the image, but there is a problem: the content of that column is the full path of the image and if I enter a word/letter which is in the path, I receive all records.

For example

This is my jTabel with getColumnClass :

and this is without getColumnClass :

If I enter "resource" in Enter value field nothing changes, because all cells have this content.

Is there any method to filter only by image name without extension (eg orange, vodafone, cosmote)?

Below is my code :

package main;

import javax.swing.DefaultCellEditor;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JLabel;

Maybe you could include the path in the regex you want to filter with? Like:

String path = "resources\/opIcons\/";
RowFilter.regexFilter("^"+path+".*"+filterValue+".*$", sortColumn)
