How to add rows to a JTable dynamically?
In my program I will add rows to a JTable dynamically. My codes look like follows:
...
...
private javax.swing.JTable jTable = null;
...
private javax.swing.JTable getJTable() {
if(jTable == null) {
jTable = new javax.swing.JTable();
}
return jTable;
}
...
...
for(int i= 0; i<5; i++)
jTable.addColumn(new javax.swing.table.TableCol
...
...
// now I will read data from a file and insert into the table.
try{
BufferedReader in = new BufferedReader(new FileReader(tableFileName))
String line;
while((line = in.readLine()) != null)
{
// here a row will be added to jtable;
}
...
...
...
...
private javax.swing.JTable jTable = null;
...
private javax.swing.JTable getJTable() {
if(jTable == null) {
jTable = new javax.swing.JTable();
}
return jTable;
}
...
...
for(int i= 0; i<5; i++)
jTable.addColumn(new javax.swing.table.TableCol
...
...
// now I will read data from a file and insert into the table.
try{
BufferedReader in = new BufferedReader(new FileReader(tableFileName))
String line;
while((line = in.readLine()) != null)
{
// here a row will be added to jtable;
}
...
...

You can use DefaultTableModel or write your own model. It is very easy. These models identify the change by itself and would update the JTable automatically. You dont have to worry abt forcing the updates

Thanks, it works. But How can I set the table cell non-editable?

That's another Q isn't it?
>>How can I set the table cell non-editable?
Use your own TableModel (extending DefaultTableModel).
and overwrite the function
boolean isCellEditable(int row, int column) {
if (column==1)
return false; // makes the 2nd column non-editable
return true;
}

Thanks for accepting
E.g. column1Data,column2 Data,Data3,Data4,Data5
while((line = in.readLine()) != null) {
model.addRow( line.split(",") );
}
