The TableModel interface specifies the methods the JTable will use to interrogate a tabular data model.

The JTable can be set up to display any data model which implements the TableModel interface with a couple of lines of code: 

  	TableModel myData = new MyTableModel(); 
  	JTable table = new JTable(myData);

For further documentation, see Creating a Table Model in The Java Tutorial.

JTable
Adds a listener to the list that is notified each time a change to the data model occurs.
Parameters
lthe TableModelListener
Returns the most specific superclass for all the cell values in the column. This is used by the JTable to set up a default renderer and editor for the column.
Parameters
columnIndexthe index of the column
Return
the common ancestor class of the object values in the model.
Returns the number of columns in the model. A JTable uses this method to determine how many columns it should create and display by default.
Return
the number of columns in the model
See Also
#getRowCount
Returns the name of the column at columnIndex. This is used to initialize the table's column header name. Note: this name does not need to be unique; two columns in a table can have the same name.
Parameters
columnIndexthe index of the column
Return
the name of the column
Returns the number of rows in the model. A JTable uses this method to determine how many rows it should display. This method should be quick, as it is called frequently during rendering.
Return
the number of rows in the model
See Also
#getColumnCount
Returns the value for the cell at columnIndex and rowIndex.
Parameters
rowIndexthe row whose value is to be queried
columnIndexthe column whose value is to be queried
Return
the value Object at the specified cell
Returns true if the cell at rowIndex and columnIndex is editable. Otherwise, setValueAt on the cell will not change the value of that cell.
Parameters
rowIndexthe row whose value to be queried
columnIndexthe column whose value to be queried
Return
true if the cell is editable
See Also
#setValueAt
Removes a listener from the list that is notified each time a change to the data model occurs.
Parameters
lthe TableModelListener
Sets the value in the cell at columnIndex and rowIndex to aValue.
Parameters

rowIndexthe row whose value is to be changed
columnIndexthe column whose value is to be changed
