Font Size, Color and Styles in Apple Notes changes between iPad, iPhone and Mac

When making an Apple note with tables the font size, text color and style can change in an unpleasant way.

• The font size changes into a smaller size.
• The character color changes from black to yellow especialy when using more than one group of numbers per cell
• The character suddenly are underlined without any reason.

My experience is that editing a table cell on the iPad notes version is the main cause.

You may have some results to change the font on the Mac version, but general creating a new table with same settings is the only way to get rid of this nasty behaviour.
