Change data in jTable

Hi,

I need to change data in a jtable using default table model.

But the following piece of code just doesn't change the table content. The j table is contained in a scroll panel. Can someone point me to the right direction to debug the problem? Thanks,

Object[][] newTableData = { {"5","6","7","8"}, {"AA", "BB", "CC", "DD"} };

String[] ColumnHeaders = {"Title", "Rating", "Date", "Genre"};

jTableMovies = new JTable(newTableData, ColumnHeaders);
