When i change the default font in LO Draw styles → Default ->Modify->fonts. This changes only the text in text tool and not in tables. Can i get help?
Sadly, tables are not managed by styles (yet?). The “table styles” you can see in Draw or Writer are indeed just a collection of “templates” that cannot be modified. What you can do is to select all cells in a table and then apply a text style. For example, apply the “Predefined” style to get the font predefined for the document.
