Question

You can create a table model and add it to a table

TableModel tm = new TableModel();
JTable table = new JTable(tm);

however, if I init a Table

JTable table = new JTable();

and then create a table model later on…

TableModel tm = new TableModel();
tm.addValueAt(...);
...

Is there a way I can add this table model to the original table?

I’ve actually created my own classes to extend TableModel and JTable, and I thought that I could simply reconstruct the table given the new table model, but this doesn’t seem to work.

Answer 1

As stated here: JTable, You can use setModel(TableModel)

public void setModel(TableModel dataModel)

Sets the data model for
this table to newModel and registers with it for listener
notifications from the new data model.
