Package Summary Overview Summary

class:TableModel [NONE]

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 .

JTable

method:getRowCount() [NONE]

getRowCount
```
int getRowCount()
```
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.

Returns:

the number of rows in the model

See Also:

getColumnCount()

method:getColumnCount() [NONE]

getColumnCount
```
int getColumnCount()
```
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.

Returns:

the number of columns in the model

See Also:

getRowCount()

method:getColumnName(int) [NONE]

getColumnName
```
String getColumnName(int columnIndex)
```
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:

columnIndex - the index of the column

Returns:

the name of the column

method:getColumnClass(int) [NONE]

getColumnClass
```
Class<?> getColumnClass(int columnIndex)
```
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:

columnIndex - the index of the column

Returns:

the common ancestor class of the object values in the model.

method:isCellEditable(int,int) [NONE]

isCellEditable
```
boolean isCellEditable(int rowIndex,
                       int columnIndex)
```
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:

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:

setValueAt(java.lang.Object, int, int)

method:getValueAt(int,int) [NONE]

getValueAt
```
Object getValueAt(int rowIndex,
                  int columnIndex)
```
Returns the value for the cell at columnIndex and rowIndex.

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

method:setValueAt(java.lang.Object,int,int) [NONE]

setValueAt
```
void setValueAt(Object aValue,
                int rowIndex,
                int columnIndex)
```
Sets the value in the cell at columnIndex and rowIndex to aValue.

Parameters:

aValue - the new value

rowIndex - the row whose value is to be changed

columnIndex - the column whose value is to be changed

See Also:

getValueAt(int, int) , isCellEditable(int, int)

method:addTableModelListener(javax.swing.event.TableModelListener) [NONE]

addTableModelListener
```
void addTableModelListener(TableModelListener l)
```
Adds a listener to the list that is notified each time a change to the data model occurs.

Parameters:

l - the TableModelListener

method:removeTableModelListener(javax.swing.event.TableModelListener) [NONE]

removeTableModelListener
```
void removeTableModelListener(TableModelListener l)
```
Removes a listener from the list that is notified each time a change to the data model occurs.

Parameters:

l - the TableModelListener
