I have a jTable
which loads data from a DB query
This load produces 32 results, thus 32 rows in the TableModel
With myTable.getRowCount()
Can you post a verifiable code of yours? because i tried with the following code and the model changed without any issues.
public static void main(String[] args) throws InterruptedException {
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
DefaultTableModel model = new DefaultTableModel(
new Object[][] { { "some", "text" }, { "any", "text" },
{ "even", "more" }, { "text", "strings" },
{ "and", "other" }, { "text", "values" } },
new Object[] { "Column 1", "Column 2" });
String[] columnNames= {null};
DefaultTableModel model1 = new DefaultTableModel(null,columnNames);
model1.setRowCount(0);
JTable table = new JTable(model);
JScrollPane scrollPane = new JScrollPane(table);
frame.add(scrollPane, BorderLayout.CENTER);
frame.setSize(300, 150);
frame.setVisible(true);
Thread.sleep(5000);
table.setModel(model1);
}
