            label_prefix (str): Prefix string applied to the page label, preceding the numeric portion.

        This method allows printing text with line breaks. They can be automatic
        (breaking at the most recent space or soft-hyphen character) as soon as the text
        reaches the right border of the cell, or explicit (via the `\\n` character).
        As many cells as necessary are stacked, one below the other.
        Text can be aligned, centered or justified. The cell block can be framed and
        the background painted. A cell has an horizontal padding, on the left & right sides,
        defined by the.c_margin property.

        Args:
            w (float): cell width. If 0, they extend up to the right margin of the page.
            h (float): height of a single line of text.  Default value: None, meaning to use the current font size.
            text (str): string to print.
            border: Indicates if borders must be drawn around the cell.
                The value can be either a number (`0`: no border ; `1`: frame)
                or a string containing some or all of the following characters
                (in any order):
                `L`: left ; `T`: top ; `R`: right ; `B`: bottom. Default value: 0.
            align (fpdf.enums.Align, str): Set text alignment inside the cell.
                Possible values are:
                `J`: justify (default value); `L` or empty string: left align;
                `C`: center; `X`: center around current x position; `R`: right align
            fill (bool): Indicates if the cell background must be painted (`True`)
                or transparent (`False`). Default value: False.
            split_only (bool): **DEPRECATED since 2.7.4**:
                Use `dry_run=True` and `output=("LINES",)` instead.
            link (str): optional link to add on the cell, internal
                (identifier returned by `add_link`) or external URL.
            new_x (fpdf.enums.XPos, str): New current position in x after the call. Default: RIGHT
            new_y (fpdf.enums.YPos, str): New current position in y after the call. Default: NEXT
            ln (int): **DEPRECATED since 2.5.1**: Use `new_x` and `new_y` instead.
            max_line_height (float): optional maximum height of each sub-cell generated
            markdown (bool): enable minimal markdown-like markup to render part
                of text as bold / italics / strikethrough / underlined.
                Supports `\\` as escape character. Default to False.
            print_sh (bool): Treat a soft-hyphen (\\u00ad) as a normal printable
                character, instead of a line breaking opportunity. Default value: False
            wrapmode (fpdf.enums.WrapMode): "WORD" for word based line wrapping (default),
                "CHAR" for character based line wrapping.
            dry_run (bool): if `True`, does not output anything in the document.
                Can be useful when combined with `output`.
            output (fpdf.enums.MethodReturnValue): defines what this method returns.
                If several enum values are joined, the result will be a tuple.
            txt (str): [**DEPRECATED since v2.7.6**] string to print.
            center (bool): center the cell horizontally on the page.
            padding (float or Sequence): padding to apply around the text. Default value: 0.
                When one value is specified, it applies the same padding to all four sides.
                When two values are specified, the first padding applies to the top and bottom, the second to
                the left and right. When three values are specified, the first padding applies to the top,
                the second to the right and left, the third to the bottom. When four values are specified,
                the paddings apply to the top, right, bottom, and left in that order (clockwise)
                If padding for left or right ends up being non-zero then respective c_margin is ignored.

        Center overrides values for horizontal padding

        Using `new_x=XPos.RIGHT, new_y=XPos.TOP, maximum height=pdf.font_size` is
        useful to build tables with multiline text in cells.
