Methods

 o addColumn
public void addColumn(TableColumn aColumn)
Appends aColumn to the end of the receiver's tableColumns array. This method also posts the columnAdded() event to its listeners.

Parameters:
column - The TableColumn to be added
Throws: IllegalArgumentException
if aColumn is null
See Also:
removeColumn
 o removeColumn
public void removeColumn(TableColumn column)
Deletes the TableColumn column from the receiver's table columns array. This method will do nothing if column is not in the table's columns list. tile() is called to resize both the header and table views. This method also posts the columnRemoved() event to its listeners.

Parameters:
column - The TableColumn to be removed
See Also:
addColumn
 o moveColumn
public void moveColumn(int columnIndex,
                       int newIndex)
Moves the column and heading at columnIndex to newIndex. The old column at columnIndex will now be found at newIndex, The column that used to be at newIndex is shifted left or right to make room. This will not move any columns if columnIndex equals newIndex. This method also posts the columnMoved() event to its listeners.

Parameters:
columnIndex - the index of column to be moved
newIndex - New index to move the column
Throws: IllegalArgumentException
if column or newIndex are not in the valid range
 o setColumnMargin
public void setColumnMargin(int newMargin)
Sets the column margin to newMargin. This method also posts the columnMarginChanged() event to its listeners.

Parameters:
newMargin - the width margin of the column
See Also:
getColumnMargin, getTotalColumnWidth
 o getColumnCount
public int getColumnCount()
Returns the number of columns in the receiver's table columns array.

Returns:
the number of columns in the receiver's table columns array
See Also:
getColumns
 o getColumns
public Enumeration getColumns()
Returns an Enumeration of all the columns in the model

 o getColumnIndex
public int getColumnIndex(Object identifier)
Returns the index of the first column in the receiver's columns array whose identifier is equal to identifier, when compared using equals(). Returns -1 if no column is found with the specified identifier.

Parameters:
identifier - the identifier object
Returns:
the index of the first table column in the receiver's tableColumns array whose identifier is equal to identifier, when compared using equals().
Throws: IllegalArgumentException
