Code before:
        row_alignments: Optional[str] = None,  # "ucd"
        col_alignments: Optional[str] = None,  # "lcr"
        row_heights: Optional[Iterable[Optional[float]]] = None,
        col_widths: Optional[Iterable[Optional[float]]] = None,
        flow_order: str = "rd",
        **kwargs,
    ) -> "Mobject":
        """Arrange submobjects in a grid.

        Parameters
        ----------
        rows
            The number of rows in the grid.
        cols
            The number of columns in the grid.
        buff
            The gap between grid cells. To specify a different buffer in the horizontal and
            vertical directions, a tuple of two values can be given - `(row, col)`.
        cell_alignment
            The way each submobject is aligned in its grid cell.
        row_alignments
            The vertical alignment for each row (top to bottom). Accepts the following characters: `"u"` -
            up, `"c"` - center, `"d"` - down.
        col_alignments
            The horizontal alignment for each column (left to right). Accepts the following characters `"l"` - left,
             `"c"` - center, `"r"` - right.
        row_heights
            Defines a list of heights for certain rows (top to bottom). If the list contains `None`, the corresponding row will fit its height automatically based
            on the highest element in that row.
        col_widths
            Defines a list of widths for certain columns (left to right). If the list contains `None`, the
            corresponding column will fit its width automatically based on the widest element in that column.
        flow_order
            The order in which the grid gets filled with the submobjects. Can be one of the
            following values: "rd", "dr", "ld", "dl", "ru", "ur", "lu", "ul". For example,
            "dr" (down right) means: Fill the table column by column downwards, filling the
            columns rigthwards. "u" and "l" stand for upwards and leftwards.

        Returns
        -------
        Mobject
            The mobject.

        NOTES
        -----

        .. note::
            If either :code:`rows` or :code:`cols` is not defined, it is set to the length of either
            :code:`row_alignments` / :code:`col_alignments` or :code:`row_heights` / :code:`col_widths` if
            one of those is defined. If only one of :code:`rows` and :code:`cols` can be determined
            like this, the other will be choosen big enough to fit all submobjects.

Review comment (suggestion):
In the rendered page, there is some unfortunate formatting going on with this parameter (I think I might have introduced the error 😅). This should fix it.
```suggestion
        col_alignments
            The horizontal alignment for each column (left to right). Accepts the following characters `"l"` - 
            left, `"c"` - center, `"r"` - right.
```

        """Arrange submobjects in a grid.

        Parameters
        ----------
        rows
            The number of rows in the grid.
        cols
            The number of columns in the grid.
        buff
            The gap between grid cells. To specify a different buffer in the horizontal and
            vertical directions, a tuple of two values can be given - ``(row, col)``.
        cell_alignment
            The way each submobject is aligned in its grid cell.
        row_alignments
            The vertical alignment for each row (top to bottom). Accepts the following characters: ``"u"`` -
            up, ``"c"`` - center, ``"d"`` - down.
        col_alignments
            The horizontal alignment for each column (left to right). Accepts the following characters ``"l"`` - left,
            ``"c"`` - center, ``"r"`` - right.
        row_heights
            Defines a list of heights for certain rows (top to bottom). If the list contains
            ``None``, the corresponding row will fit its height automatically based
            on the highest element in that row.
        col_widths
            Defines a list of widths for certain columns (left to right). If the list contains ``None``, the
            corresponding column will fit its width automatically based on the widest element in that column.
        flow_order
            The order in which submobjects fill the grid. Can be one of the following values:
            "rd", "dr", "ld", "dl", "ru", "ur", "lu", "ul". ("rd" -> fill rightwards then downwards)

        Returns
        -------
        Mobject
            The mobject.

        NOTES
        -----

        If only one of ``cols`` and ``rows`` is set implicitly, the other one will be chosen big
        enough to fit all submobjects. If neither is set, they will be chosen to be about the same,
        tending towards ``cols`` > ``rows`` (simply because videos are wider than they are high).
