Hi turnermm,
thanks for your answer.
After searching the whole Internet I found for myself a solution for that Problem! Now I'm able to make all table formattings and save them for use with dokuwiki.
The only thing that I had to do is inserting following macro-tag in the ckeditor bevor and after my table:
~~START_HTML_BLOCK~~
<inserting her my table from the ckeditor>
~~CLOSE_HTML_BLOCK~~
after that, I was able to save my table and all those settings in the ckeditor. :-)
It's not perfect, but nice and it works for me!
btw: you are the author of the Plugin ckgedit, right?
Kind regards,
Roli
