Love Coda. Would love even more when I’m able to “copy and paste” a column format to other column. Like the “Format Painter” from Excel or Sheets.
Or even crtl+select more than one column and change their format in one go.
Hope you guys are planning on implementing that. 
I completely agree that there’s a need for this!
Something else that would (at least in part) solve this problem is if a column could inherit the format from a column it is referencing.
E.g. if I’ve got a column formatted as a currency with a divider for 1,000 and no decimals, and I reference that column from another column, I’d like that other column to default to the same formatting.
