How to display a 2D array in jTable?
I have a static 2D array called Status.Data[][]
and a Column header called Status.Columns[]
.
I am using net beans and I want to be able to have the arrays populate the table.
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
jTable1.setColumnModel(new DefaultColumnModel(Status.Data, Status.Columns));
}
This throws an error that it is expecting a TableColumnModel.
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
jTable1.setColumnMo开发者_如何学JAVAdel(new TableColumnModel(Status.Data, Status.Columns));
}
This says java.swing.table.TableColumnModel is abstract and cannot be instantiated.
I would even be happy if I could figure out how to make it display when the window is opened.
How do I populate my table?
You can create the table model and then pass it to the table constructor:
TableModel model = new DefaultTableModel(Status.Data, Status.Columns);
JTable table = new JTable(model);
use javax.swing.table.DefaultTableModel
DefaultTableModel(Object[][] data, Object[] columnNames)
