default table model editable

Question

I have two questions about jtable and default table model

JTable  table = new JTable();
TableModel model = new DefaultTableModel(colNames,rowcount);
table.setModel(model);

1. I had comboBox added to column 4 and only column 4 should be editable and rest should be not be editable. How to make only column 4 editable?
2. the rows for the table are coming from ms access table, so if the comboBox is changed, I would like to update it in the ms access table too. How to update the data in ms access table?

Answer 1

You'll need to proceed in several steps:

• Start with How to Use Tables.

• This example illustrates Using a Combo Box as an Editor.

• This example shows how to override setValueAt(), from which you can update your database using JDBC.

• Once you understand these concepts, consider DbUtils.
