JTable Control Add Delete Row __jtable

To add a row:

You cannot insert rows directly into JTable, and you need the help of JTable's TableModel code as follows:

Import Javax.swing.table.DefaultTableModel;

Import javax.swing.JTable;

。。。

JTable table = new JTable ();

DefaultTableModel model = (DefaultTableModel) Table.getmodel ();

Model.add (New string[]{"xxxxxxx", "Yyyyyy", "zzzzzzz"});

。。。
Delete Row:

Using the Model.removerow (index) method

Get the number of records:

You can use the GetRowCount () method of jtable directly, or you can use its model GetRowCount () method

Empty jtable:

Using the Model.setrowcount (0) method

To get JTable data:

It seems that the data can only be retrieved in vector form using the Getdatavector () method:

Import Java.util.Vector;
...

Vector data = ((DefaultTableModel) Tbinfo.getmodel ()). Getdatavector ();

The Vector object is also the vector object of the element data.

Get one row of data:

Vector rowdata =data.get (1);

Gets a data grid, a data in one row of data:

Vector rowdata =data.get (1);

String field = Rowdata.get (1);
