Removing unused Rows from jTable

How do I remove unused rows from a JTable?

I first create a table of a fixed size in a JPanel and then fill elements as needed.

Now I don't want unused rows to be displayed in my table. Please help.

Solution

  • I presently get a table with lots of empty rows in bottom, only top 5-6 rows being used, with rest blank. I want to hide them or remove them somehow

    Work the other way around. Start with an empty DefaultTableModel. DefaultTableModel supports an addRow() method. So, as you get data to add to the model use:

    model.addRow(...);

    Don't let the GUI editor determine how you code your GUI. Adding cleanup code to remove rows is a bad design.
