 | -------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
 | `inner`  | Returns row with matching keys in _both_ frames. Non-matching rows in either the left or right frame are discarded.                                                                                        |
 | `left`   | Returns all rows in the left dataframe, whether or not a match in the right-frame is found. Non-matching rows have their right columns null-filled.                                                        |
-| `right`   | Returns all rows in the right dataframe, whether or not a match in the left-frame is found. Non-matching rows have their left columns null-filled.                                                        |
+| `right`  | Returns all rows in the right dataframe, whether or not a match in the left-frame is found. Non-matching rows have their left columns null-filled.                                                         |
 | `full`   | Returns all rows from both the left and right dataframe. If no match is found in one frame, columns from the other frame are null-filled.                                                                  |
 | `cross`  | Returns the Cartesian product of all rows from the left frame with all rows from the right frame. Duplicates rows are retained; the table length of `A` cross-joined with `B` is always `len(A) × len(B)`. |
 | `semi`   | Returns all rows from the left frame in which the join key is also present in the right frame.                                                                                                             |
