Use Swing to implement the data table function (add to the essence Area)

A recent project was developed by delphi, where data tables are used in many areas. This function can be easily implemented in delphi and vb. java does not
This function is provided, but can be implemented using Jtable, but it is a bit of trouble :).
The following is a simple data table program code that I implemented using applet.
Package com. applet. cat10;
Import java. awt .*;
Import java. awt. event .*;
Import java. applet .*;
Import javax. swing .*;
Import com. util .*;
Import java. util .*;
Import javax. swing. table .*;
Import java. SQL .*;

Boolean isStandalone = false;
JButton jButton1 = new JButton (); // trigger time query button

DefaultTableModel dtm; // defines the table data model.
