(Assuming you're trying to do this so you count left to right top to bottom and have 8 columns)

You need to offset the value each time for the number of columns you've seen. Every time you iterate through an entire row, you've seen 8 columns, so it's not sufficient to add i and j, you need to add rows seen (i) multiplied by the number of columns (8). Thus you should be printing i*8 + j:

for (int j = 0; j < 8; j++) {  
    for (int i = 0; i < 8; i++) {  
        table.setValueAt(""+(i*8+j), i, j);
    }
}
