It would be great if it was possible to FORMAT TEXT (fonts, colors, bold, italics), CELLS (left, right, center alignment, background colors), and BORDERS (bold or dashed lines, colors) within tables. The ability to add extra header lines and/or to FREEZE more cells vertically and horizontally would help, too.
I really like the idea of Airtable, but can’t effectively use it over Excel until it has more functionality.
