* add signature information when help on one command * tell user that one command support operated on cell paths Also, make type output to be more friendly, like `record<>` should just be `record` And the same to `table<>`, which should be `table` * simplify code * don't show signatures for parser keyword * update comment * output arg syntax shape as type, so it's the same as describe command * fix string when no positional args * update signature body * update * add help signature test * fix arg output format for composed data type like list or record * fix clippy * add comment
