java.lang.ArrayIndexOutOfBoundsException: 0 >= 0 attempting to populate JTable

Question

I\'m subclassing JTable and using a DefaultTableModel to model my table data. The following class sets up the JTable, and adds one row to the model.

import          


        

Answer 1

Dmitry is right, but you simply have to update your model. To do this, add the following to your code:

DefaultTableModel dtm = (DefaultTableModel) table.getModel();
for (int c = 0; c < table.getColumnCount(); c++) {
dtm.addColumn(table.getColumnName(c));
}
