This is correct.

This is not correct. It is also aligned w.r.t the current line width.
Reason is that the table and the diversions are not processed at the
same time.

This is caused by the PSPIC macro. See attached example for a
solution.

Again, this is not correct. Please write again if the attached
`table-test' doesn't give a sufficient explanation.

package.

Here's the inner table's diversion, using a centered image (d1). Remember
that the table's column modifier `w' gives a \fIminimum\fR width! To get a
correct width of the surrounding box it is necessary to modify the `PSPIC'
macro; by default, it doesn't move the current point to the right edge of
the image.
