@derekagorhom that's fine as far as it goes. Here is the dialog now:

Usually I would suggest we could merge this and then you continue. But here there is no point, because the dialog doesn'r do anything until you start yo implement at least one of the saving methods - in addition to html. That's the whole point now, of this dialog. Later there will be more. So please can you proceed, perhaps starting with the Word option, though you may find that as soon as you do one you can do them all. Ask @Patowhiz pr @N-thony if you need help. It looks reasonably straightforward in the gt documentation?

@derekagorhom I assume you are still working on this, as still nothing is enabled. I'm keen also for something in addition from html, which is the default anyway.

@rdstern I have enabled the export options now.
i used gtsave function for the export
gtsave(data, filename, path = NULL, ...)
i allowed the path in which the tables should be exported into to be the my documents folder for the user.
the only problem is from the word option, while trying it i encountered this error.

Apart from the word option, the other options seem to work fine.
Thanks

@derekagorhom that seems like an excellent start. @Patowhiz maybe you could check, so far, and also see whether there is an obvious fix to theWord export?
I wonder as follows:
a) Could the export work for multiple tables at the same time? So could we change the receiver to be a multiple receiver, and export them all into one word, rtf or LaTex file?
b) Later I hope there will be options to improve the gt table object as well. So the export will become just one option from this dialog. When used, should we replace the Store Table option with an Export File dialog. This should then be like the dialogs in the File > Export dialog, so we can choose where to save the exported file?
