hi everyone, I have a DefaultTableModel that I built with tableModel.addColumn("dasdasfasfs"), thereafter I fill it with addRow.
I want to reuse the tableModel, but before I want to clear it (rows and columns) to add different columns and different rows.
for the rows:
for (int i = 0; i < this.tableModel.getRowCount(); i++) {
this.tableModel.removeRow(i);
}
but don't know how to remove the columns
thanks
