Add row to top of AbstractTableModel

Question

I have a abstractTableModel which I need to add rows to the top, so the user can see the most recent entered data, but default it adds to the bottom of the table. Any suggestions?

Answer 1

• override public void insertRow(int row, Vector rowData)

• this code block must contains proper notifiers fireTableRowsInserted(int firstRow, int lastRow), otherwise no row is showed in JTables view

• all updates must be done on EDT, more in Oracle tutorial The Event Dispatch Thread

• code eamples in Oracle tutorial How to use Tables - Creating a Table Mode

Answer 2

If the AbstractTableModel is using List then just while adding the object to the list add it at the zeroth position in the list.

list.add(0, object);

and call respective fireXXXMethod

So now all the objects that are present will move to 1 postion up the list.
