Well, maybe session is indeed what you want.

Some user has been working an interface to integrate graphiz with
TeXmacs. That interface essentially allows a programatic description
to be translated in an included picture. You should be able to look
for it on the user contribution sections of the Wiki, but I cannot be
more precise since the Wike seems to be down right now.

I think that is near to what you want: given the name of the raw data
file, you get the table.

Hybrid is not what you want. I documented it on the Wiki...
Essentially it is a container used by the editor when typing backslash
shortcuts.

Specific is not what you want either. It allows you to include some
code wich is only used when exporting to a specific file format. It is
what is closest to the LyX "red text" in TeXmacs. But it is *really*
seldom used.

Action might be remotely related to what you want to do. It can be
used to associate a piece of text to some GUILE code. When the piece
of text is double-clicked, the scheme code is evaluated. But,
actually, I have never seen a real-world use of this.

What is on your mind?

We are thinking a lot about collaborative documents. Well not quite
right now, because we are thinking a lot about GUI issues, but
collaborative work is an important planned feature.

After I saw your posts on address@hidden, I think the best way to do
what you want would be along the following lines:

Use some tool to generate a TeXmacs document in Scheme format
containing your table. You may use an external Perl script or an
embedded guile script (there must be some regex module in your guile
distribution).

Then "File->Import->Scheme" to open the document, copy the table,
close the document, paste the table, remove the document.

Maybe even all of this could be automated in GUILE and use the "get
file" dialog of TeXmacs.

Hope this helps.
