void moveColumn(int columnIndex, int newIndex)
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

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
accommodate 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.JTable.columnAtPoint(java.awt.Point)
