When automatic drag handling is enabled,
most look and feels begin a drag-and-drop operation

Setting this property to true
can therefore have a subtle effect on
how selections behave.
Some look and feels might not support automatic drag and drop;
they will ignore this property. You can work around such

JTable provides all the methods for handling
column and row selection. When setting states,
such as setSelectionMode, it not only
updates the mode for the row selection model but also sets similar
values in the selection model of the columnModel.
If you want to have the row and column selection models operating
in different modes, set them both directly.
Both the row and column selection models for JTable
default to using a DefaultListSelectionModel
so that JTable works the same way as the
JList. See the setSelectionMode method
in JList for details about the modes.

public Rectangle getCellRect(int row,
int column,
boolean includeSpacing)
row and column.
If includeSpacing is true then the value returned
has the full height and width of the row and column
specified. If it is false, the returned rectangle is inset by the
intercell spacing to return the true bounds of the rendering or
editing component as it will be set during rendering.
If the column index is valid but the row index is less
than zero the method returns a rectangle with the
y and height values set appropriately
and the x and width values both set
to zero. In general, when either the row or column indices indicate a
cell outside the appropriate range, the method returns a rectangle
depicting the closest edge of the closest cell that is within
the table's range. When both row and column indices are out
of range the returned rectangle covers the closest
point of the closest cell.
In all cases, calculations that use this method to calculate
results along one axis will not fail because of anomalies in
calculations along the other axis. When the cell is not valid
the includeSpacing parameter is ignored.

public void doLayout()
JTable's
columns is equal to the width of the table.
Before the layout begins the method gets the
resizingColumn of the tableHeader.
When the method is called as a result of the resizing of an enclosing window,
the resizingColumn is null. This means that resizing
has taken place "outside" the JTable and the change -
or "delta" - should be distributed to all of the columns regardless
of this JTable's automatic resize mode.
If the resizingColumn is not null, it is one of
the columns in the table that has changed size rather than
the table itself. In this case the auto-resize modes govern
the way the extra (or deficit) space is distributed
amongst the available columns.
The modes are:
Viewport. If the JTable is not
enclosed in a JScrollPane this may
leave parts of the table invisible.
JTable, including the one that is being
adjusted.
JTable makes adjustments
to the widths of the columns it respects their minimum and
maximum values absolutely. It is therefore possible that,
even after this method is called, the total width of the columns
is still not equal to the width of the table. When this happens
the JTable does not put itself
in AUTO_RESIZE_OFF mode to bring up a scroll bar, or break other
commitments of its current auto-resize mode -- instead it
allows its bounds to be set larger (or smaller) than the total of the
column minimum or maximum, meaning, either that there
will not be enough room to display all of the columns, or that the
columns will not fill the JTable's bounds.
These respectively, result in the clipping of some columns
or an area being painted in the JTable's
background color during painting.
The mechanism for distributing the delta amongst the available
columns is provided in a private method in the JTable
class:
adjustSizes(long targetSize, final Resizable3 r, boolean inverse)an explanation of which is provided in the following section.
Resizable3 is a private
interface that allows any data structure containing a collection
of elements with a size, preferred size, maximum size and minimum size
to have its elements manipulated by the algorithm.
Call "DELTA" the difference between the target size and the sum of the preferred sizes of the elements in r. The individual sizes are calculated by taking the original preferred sizes and adding a share of the DELTA - that share being based on how far each preferred size is from its limiting bound (minimum or maximum).
Call the individual constraints min[i], max[i], and pref[i].
Call their respective sums: MIN, MAX, and PREF.
Each new size will be calculated using:
size[i] = pref[i] + delta[i]
where each individual delta[i] is calculated according to:
If (DELTA < 0) we are in shrink mode where:
DELTA
delta[i] = ------------ * (pref[i] - min[i])
(PREF - MIN)
If (DELTA > 0) we are in expand mode where:
DELTA
delta[i] = ------------ * (max[i] - pref[i])
(MAX - PREF)
The overall effect is that the total size moves that same percentage, k, towards the total minimum or maximum and that percentage guarantees accomodation of the required space, DELTA.
Naive evaluation of the formulae presented here would be subject to
the aggregated rounding errors caused by doing this operation in finite
precision (using ints). To deal with this, the multiplying factor above,
is constantly recalculated and this takes account of the rounding
errors in the previous iterations. The result is an algorithm that
produces a set of integers whose values exactly sum to the supplied
targetSize, and does so by spreading the rounding
errors evenly over the given elements.
When targetSize is outside the [MIN, MAX] range,
the algorithm sets all sizes to their appropriate limiting value
(maximum or minimum).

is enabled) invokes notifyAction to notify the action.

TableColumn for this column has a non-null

Note: Throughout the table package, the internal implementations always use this method to provide renderers so that this default behavior can be safely overridden by a subclass.
