JTable won't show column headers

Question

I have the following code to instantiate a JTable: the table comes up with the right number of rows and columns, but there is no sign of the titles atop the columns.

public Panel1() {     int  nmbrRows;      setLayout(null);     setBackground(Color.magenta);     Vector colHdrs;      //create column headers      colHdrs = new Vector(10);     colHdrs.addElement(new String("Ticker"));      // more statements like the above to establish all col. titles             nmbrRows = 25;     DefaultTableModel tblModel = new DefaultTableModel(nmbrRows, colHdrs.size());     tblModel.setColumnIdentifiers(colHdrs);      scrTbl = new JTable(tblModel);     scrTbl.setBounds(25, 50, 950, 600);     scrTbl.setBackground(Color.gray);     scrTbl.setRowHeight(23);         add(scrTbl);  //rest of constructor ...  } 

Comparing this to other table-making code, I don't see any missing steps, but something must be absent.

Answer 1

Put your JTable inside a JScrollPane. Try this:

add(new JScrollPane(scrTbl));
