Appends aColumn to the end of the tableColumns array. This method posts a columnAdded event to its listeners.
Parameters
aColumnthe TableColumn to be added
See Also
Adds a listener for table column model events.
Parameters
xa TableColumnModelListener object
Returns the TableColumn object for the column at columnIndex.
Parameters
columnIndexthe index of the desired column
Return
the TableColumn object for the column at columnIndex
Returns the number of columns in the model.
Return
the number of columns in the model
Returns the index of the first column in the table whose identifier is equal to identifier, when compared using equals.
Parameters
columnIdentifierthe identifier object
Return
the index of the first table column whose identifier is equal to identifier
Throws
IllegalArgumentExceptionif identifier is null, or no TableColumn has this identifier

Returns the index of the column that lies on the horizontal point, xPosition; or -1 if it lies outside the any of the column's bounds. In keeping with Swing's separable model architecture, a TableColumnModel does not know how the table columns actually appear on screen. The visual presentation of the columns is the responsibility of the view/controller object using this model (typically JTable). The view/controller need not display the columns sequentially from left to right. For example, columns could be displayed from right to left to accomodate a locale preference or some columns might be hidden at the request of the user. Because the model does not know how the columns are laid out on screen, the given xPosition should not be considered to be a coordinate in 2D graphics space. Instead, it should be considered to be a width from the start of the first column in the model. If the column index for a given X coordinate in 2D space is required, JTable.columnAtPoint can be used instead.
Return
the index of the column; or -1 if no column is found
Returns the width between the cells in each column.
Return
the margin, in pixels, between the cells
Returns an Enumeration of all the columns in the model.
Return
an Enumeration of all the columns in the model
Returns true if columns may be selected.
Return
true if columns may be selected
Returns the number of selected columns.
Return
the number of selected columns; or 0 if no columns are selected
Returns an array of indicies of all selected columns.
Return
an array of integers containing the indicies of all selected columns; or an empty array if nothing is selected
Returns the current selection model.
Return
a ListSelectionModel object
Returns the total width of all the columns.
Return
the total computed width of all columns
Moves the column and its header 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 posts a columnMoved event to its listeners.
Parameters
columnIndexthe index of column to be moved
newIndexindex of the column's new location
Throws
IllegalArgumentExceptionif columnIndex or newIndex are not in the valid range
Deletes the TableColumn column from the tableColumns array. This method will do nothing if column is not in the table's column list. This method posts a columnRemoved event to its listeners.
Parameters
columnthe TableColumn to be removed
See Also
Removes a listener for table column model events.
Parameters
xa TableColumnModelListener object
Sets the TableColumn's column margin to newMargin. This method posts a columnMarginChanged event to its listeners.
Parameters
newMarginthe width, in pixels, of the new column margins
Sets whether the columns in this model may be selected.
Parameters
flagtrue if columns may be selected; otherwise false
Sets the selection model.
Parameters
newModela ListSelectionModel object
