gt_highlight_cols

gt_highlight_cols(
    gt,
    columns=None,
    fill='#80bcd8',
    alpha=None,
    font_weight='normal',
    font_color='#000000',
)

Add color highlighting to one or more specific columns.

The gt_highlight_cols() function takes an existing GT object and adds highlighting color to the cell background of a specific column(s).

Parameters

gt : GT

An existing GT object.

columns : SelectExpr = None

The columns to target. Can either be a single column name or a series of column names provided in a list. If None, the alignment is applied to all columns.

fill : str = '#80bcd8'

A string indicating the fill color. If nothing is provided, then "#80bcd8" (light blue) will be used as a default.

alpha : int | None = None

An integer [0, 1] for the alpha transparency value for the color as single value in the range of 0 (fully transparent) to 1 (fully opaque). If not provided the fill color will either be fully opaque or use alpha information from the color value if it is supplied in the "#RRGGBBAA" format.

font_weight : Literal['normal', 'bold', 'bolder', 'lighter'] | int = 'normal'

A string or number indicating the weight of the font. Can be a text-based keyword such as "normal", "bold", "lighter", "bolder", or, a numeric value between 1 and 1000, inclusive. Note that only variable fonts may support the numeric mapping of weight.

font_color : str = '#000000'

A string indicating the text color. If nothing is provided, then "#000000" (black) will be used as a default.

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

from great_tables import GT, md
from great_tables.data import gtcars
import gt_extras as gte

gtcars_mini = gtcars[["model", "year", "hp", "trq"]].head(8)

gt = (
    GT(gtcars_mini, rowname_col="model")
    .tab_stubhead(label=md("*Car*"))
)

gt.pipe(gte.gt_highlight_cols, columns="hp")
