Creates a font table from the RtfColor structure. When an Insert or Append operation is performed, _textColor and _backColor are either specified or the default is used. In any case, on any Insert or Append, only three colors are used. The default color of the RichTextBox (signified by a semicolon (;) without a definition), is always the first color (index 0) in the color table. The second color is always the text color, and the third is always the highlight color (color behind the text). The color table should have the form ... {\colortbl ;[TEXT_COLOR];[HIGHLIGHT_COLOR];}
