Notes

  • If no label is specified then it will be generated by formatting the name, unless no name is supplied, then it will be generated by formatting the column
  • Formatting involves converting any _'s to spaces, converting the first letter and any letter after a space to upper case and converting every other letter to lower case, e.g. "BOMB_DISPOSAL_METHOD" becomes "Bomb Disposal Method"
  • Only one of text or textcolumn should be specified when type is 'url'
