adding data after add column in jtable

Question

i have JTable with one column as default. my program can add columns with spesific value but when i try to add data in spesific row and column, an entire row filled by data. i just want to fill data to spesific row and column. its looks like this code still read number of column as default. i dont know how to solve this. thanks

for (int i = 0; i < NumberOfColumn.length; i++) {
        TableColumn tbl = new TableColumn();
        tbl.setHeaderValue(i);
        table1.getColumnModel().addColumn(tbl);

    } 
table1.setValueAt(2014, 0, 14);

for example i want to fill data '2014' at row 0 column 14, but when i run this code, all column filled with '2014'

When you manually create a TableColumn you need to specify which column in the TableModel to get the data from, otherwise they all default to column 0.

 TableColumn tbl = new TableColumn(i);
