Use the DefaultTableModel. All cells are editable by default.

Otherwise you need to override the isCellEditable(...) method of the TableModel to return true.

I gave you working code that deletes a row.

If you need more help post your SSCCE.

We don't want a .rar file or your application. We want a SSCCE.

Your SSCCE will be about 20 lines of code.

It will take a couple of lines of code to built a JTable with a few rows of data in it.

It will take a couple of lines of code to create an Action that displays the data in the row clicked.

Its takes one line of code to add the button editor to the column. (if somebody wants to test it, they will need to download the ButtonColumn class from the link given above).

It will take a few more line of code to create the Jframe and add the table to it.

I am not going to debug your custom renderer and editor. It is not an easy task to create these classes.

I already gave you a link to my blog which has a working renderer/editor which took me days to get working by looking at various solutions posted around the web. The blog even gives code for deleting a row when using this class.

My patience has run out!

So why would I post code that isn't working? Do you think the problem might be your code? I suggested you post a SSCCE showing how you used this code. I even outlined the steps needed to produce the SSCCE.

You didn't post the SSCCE. Instead you added some more verbal description which didn't help. You then complained that nobody was helping.

I again asked for the SSCCE and you posted a SSCCE using your old code. I'm tired of making suggestion 2/3 times!!!

Good luck with your next question.

This is your problem?

Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: Array index out of range: -1
at java.util.Vector.removeElementAt(Vector.java:558)
at javax.swing.table.DefaultTableModel.removeRow(DefaultTableModel.java:463)
at com.company.librarySystem.bm.ui.NewJFrame.selectedCol(NewJFrame.java:59)

Then renderers and editors have nothing to do with it. This just means that your code called the removeRow() method of DefaultTableModel and passed it a row number which wasn't in the table. The bottom line in that stack trace fragment indicates which line of your code was at fault. Start debugging there.
