GT.opt_vertical_padding

GT.opt_vertical_padding(self, scale=1.0)

Option to scale the vertical padding of the table.

This method allows us to scale the vertical padding of the table by a factor of scale. The default value is 1.0 and this method serves as a convenient shortcut for gt.tab_options(heading_padding=<new_val>, column_labels_padding=<new_val>, data_row_padding=<new_val>, row_group_padding=<new_val>, source_notes_padding=<new_val>).

Parameters

scale : float = 1.0: The factor by which to scale the vertical padding. The default value is 1.0. A value less than 1.0 will reduce the padding, and a value greater than 1.0 will increase the padding. The value must be between 0 and 3.

Returns

: GT: The GT object is returned. This is the same object that the method is called on so that we can facilitate method chaining.

Examples

Using select columns from the exibble dataset, let’s create a table with a number of components added. Following that, we’ll scale the vertical padding of the table by a factor of 3 using the opt_vertical_padding() method.

from great_tables import GT, exibble, md

gt_tbl = (
    GT(
        exibble[["num", "char", "currency", "row", "group"]],
        rowname_col="row",
        groupname_col="group"
    )
    .tab_header(
        title=md("Data listing from **exibble**"),
        subtitle=md("`exibble` is a **Great Tables** dataset.")
    )
    .fmt_number(columns="num")
    .fmt_currency(columns="currency")
    .tab_source_note(source_note="This is only a subset of the dataset.")
)

gt_tbl.opt_vertical_padding(scale=3)

This is only a subset of the dataset.

Now that’s a tall table! The overall effect of scaling the vertical padding is that the table will appear taller and there will be more buffer space between the table elements. A value of 3 is pretty extreme and is likely to be too much in most cases, so, feel free to experiment with different values when looking to increase the vertical padding.

Let’s go the other way (using a value less than 1) and try to condense the content vertically with a scale factor of 0.5. This will reduce the top and bottom padding globally and make the table appear more compact.

gt_tbl.opt_vertical_padding(scale=0.5)

	num	char	currency

A value of 0.5 provides a reasonable amount of vertical padding and the table will appear more compact. This is useful when space is limited and, in such a situation, this is a practical solution to that problem.
