You have a good start
Yopu will have to add one elemnt to the header array
to use [3] rather thean [2] as second dimention for the names array

great i got that working. but still having problem generating random majors.

Never mind i got that working . Would i be able to put this table on a .html?

[Tomas1122]

Also how would i make the rows alternate colors?

[pbl]

To make the row alternate color you need a CellRenderer
http://www.dreaminco...snippet5600.htm
make each cell return a JLabel setOpaque(true)

for the .HTML you need a JApplet. Converting from a JFrame is easy

Post your CellRendrer code and the way you attach it to your JTable

JTable t = new JTable(names, header);
		add(new JScrollPane(t));
                class MyTable extends JTable implements TableCellRenderer {
		MyTable() {
			
			super(new MyModel());
		}

	
		public TableCellRenderer getCellRenderer(int row, int col) {
			
			return this;
		}


		public Component getTableCellRendererComponent(JTable arg0,
				Object component, boolean focus, boolean arg3, int arg4, int arg5) {
			
			return (Component) component;
		}
	}

i don't think im doing this right but this is what i did. please help.

return (Component) component;

the component that you received as parameter is a String object you cannot cast it to a Component

You will have to return a JLabel who's setText() is your actual String passed as parameter component
Make the JLabel opaque(true)
based on the row number selected a background color depending if row % 2 == 0 or not
