The JTable is almost great component of Java Swing which is used to display records of any data.
Specially JTable are used for displaying records which are retrived from the database like MySQL, ORACLE ,Excel and other…
Simply JTable has it’s default model for displaying the records in format.
In this blog we would just demonstrate a simple JTable where all the data records are being assigned by developers.
Ok, here is a detail codes of Making simple JTable:
[sourcecode=’java’]
/*
* A simple program for displaying records
* in table format by using JTable Class
* of java swing Component
*
*
* Two Dimentional array is used to show data and columns
* or you can also use Vector for the datatype of
* table values and columns

column[2] = “Col3”;
column[3] = “Col4”;
column[4] = “Col5”;
//>>>>>>>>>>>>>>Two Dimensional Array <<<<<<<<<<<<<<<<<<<<<<<<<<<
//declaring the Object as String[][] with it's capability
data = new String[10][5];
/* Looping for the assigning value of data*/
for(int i = 0; i< 10; i++){
for(int j = 0; j<5; j++)
data[i][j] = "Record: Row:"+(i+1) +"Column: " +(j+1);
}
table = new JTable(data,column);
table.setFillsViewportHeight(true);
//For the scroll of the table records and Column visible
scroll = new JScrollPane(table);
//AT last adding at container of JFrame
frame.getContentPane().add(scroll);
frame.setVisible(true); //show
frame.setSize(900,300); //Frame size
}
public static void main(String[] args){
//Compile and Excute constructor
new JTableTest();
}
}

The output of the following codes shows like this:
