• Improved Word compatibility;
• Applied feedback;

[YousefED]

• The Inter font doesn't load on libreoffice
• libreoffice still shows border around caption
• in Word, Links are not styled (blue / underlined)
• in Word, "Open Video" (and file / audio) have the wrong font
• Documentation is missing (take docx as reference)

Table widths:

• the default tables are full width on libreoffice
• Explicit table widths (when you resize one column to be larger) don't work on either libreoffice or word

[areknawo]

• Fixed font loading in LibreOffice;
• Fixed link styling in Word;
• Added documentation;
• Fixed table width rendering;
• Added default column width, instead of auto;
• Removed components.tsx, using JSX elements directly;

libreoffice still shows border around caption

It seems that border/frame is not customizable, even directly from the LibreOffice.
