I created a table and set my headers with the colors and font.
To help us help you, some before and after shots will show us what you see:
- Please post a screen shot of the table that you created and saved as a new style.
- Please post a screen shot of the new table to which you applied the new style.
- What attributes are you trying to save as a new style?
I did some testing, and a style does not save every attribute.
Table 1 has a Header Row, a Footer Row and a Header Column and is the style I saved.
Table 2 is an new table set to that style.
(I typed the entries in Table 2).
Edit: I am thinking that if you want a copy with all attributes saved, Menu > File > Save as Template for future use.
