Method Detail

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:
aColumn - The TableColumn to be added

removeColumn(javax.swing.table.TableColumn)

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. This method also posts the columnRemoved() event to its listeners.
Parameters:
column - The TableColumn to be removed

addColumn(javax.swing.table.TableColumn)

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

setColumnMargin

Sets the TableColumn's 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()

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 - if identifier is null or no TableColumn has this identifier
