Hi,
I've just added width/heightDetails methods following Paul's
suggestion. I kept a duplicate of all on-the-fly grob size
calculations; it is necessary to ensure that the table cells adjust to
the content which can be subsequently edited (e.g changing the
colnames to plotmath expressions). Drawing the full iris dataset (150
x 5) takes 12 seconds when it was 8 seconds before. It is still
reasonable; I don't think anyone would want to use it for huge tables
anyway.
Out of curiosity, could drawDetails and height/widthDetails be altered
to share some information (thereby avoiding such duplication of
calculations at drawing time), or do they have to be completely
independent in the implementation?
In theory, you could cache information from drawing (such as where on
the device you drew), but this would have to be updated if the device is
resized (or output is copied between devices) and there is no general
infrastructure to support that at the moment.
PLUS width/height calculations can be performed independently of
drawing. I might want to position some output based on where a grob
WOULD be drawn, but without actually drawing the grob. So it would not
be safe, for example, for widthDetails() to assume that drawDetails()
had previously been called.
These are not insurmountable problems; they are just examples to show
that the implementation would be non-trivial.

Or the same drawing calculations have to be repeated within
width/heightDetails - those methods should get run within the same graphical
context as the drawDetails method.
Yes, the idea crossed my mind, but I did not find it very appealing
(already the function is slower than it could/should be). Something to
consider though, in a future version.
Thanks,
