Interface TableModel
- All Known Implementing Classes:
- AbstractTableModel,- DefaultTableModel
public interface TableModel
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.

Method Details- 
getRowCountint getRowCount()Returns the number of rows in the model. AJTableuses this method to determine how many rows it should display. This method should be quick, as it is called frequently during rendering.- Returns:
- the number of rows in the model
- See Also:
 
- 
getColumnCountint getColumnCount()Returns the number of columns in the model. AJTableuses this method to determine how many columns it should create and display by default.- Returns:
- the number of columns in the model
- See Also:
 
- 
getColumnNameReturns the name of the column atcolumnIndex. 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:
- columnIndex- the index of the column
- Returns:
- the name of the column
 
- 
getColumnClassReturns the most specific superclass for all the cell values in the column. This is used by theJTableto set up a default renderer and editor for the column.- Parameters:
- columnIndex- the index of the column
- Returns:
- the common ancestor class of the object values in the model.
 
- 
isCellEditableboolean isCellEditable(int rowIndex, int columnIndex) Returns true if the cell atrowIndexandcolumnIndexis editable. Otherwise,setValueAton the cell will not change the value of that cell.- Parameters:
- rowIndex- the row whose value to be queried
- columnIndex- the column whose value to be queried
- Returns:
- true if the cell is editable
- See Also:
 
- 
getValueAtReturns the value for the cell atcolumnIndexandrowIndex.- Parameters:
- rowIndex- the row whose value is to be queried
- columnIndex- the column whose value is to be queried
- Returns:
- the value Object at the specified cell
 
- 
setValueAtSets the value in the cell atcolumnIndexandrowIndextoaValue.- Parameters:
- aValue- the new value
- rowIndex- the row whose value is to be changed
- columnIndex- the column whose value is to be changed

addTableModelListenerAdds a listener to the list that is notified each time a change to the data model occurs.- Parameters:
- l- the TableModelListener
 
- 
removeTableModelListenerRemoves a listener from the list that is notified each time a change to the data model occurs.- Parameters:
- l- the TableModelListener
