Format values as integers.

With numeric values in one or more table columns, we can perform number-based formatting so that the targeted values are always rendered as integer values.

We can have fine control over integer formatting with the following options:

• digit grouping separators: options to enable/disable digit separators and provide a choice of separator symbol
• scaling: we can choose to scale targeted values by a multiplier value
• large-number suffixing: larger figures (thousands, millions, etc.) can be autoscaled and decorated with the appropriate suffixes
• pattern: option to use a text pattern for decoration of the formatted values
• locale-based formatting: providing a locale ID will result in number formatting specific to the chosen locale

Parameters

columns : SelectExpr = None

The columns to target. Can either be a single column name or a series of column names provided in a list.

rows : int | list[int] | None = None

In conjunction with columns=, we can specify which of their rows should undergo formatting. The default is all rows, resulting in all rows in targeted columns being formatted. Alternatively, we can supply a list of row indices.

use_seps : bool = True

The use_seps option allows for the use of digit group separators. The type of digit group separator is set by sep_mark and overridden if a locale ID is provided to locale. This setting is True by default.

scale_by : float = 1

All numeric values will be multiplied by the scale_by value before undergoing formatting. Since the default value is 1, no values will be changed unless a different multiplier value is supplied.

accounting : bool = False

Whether to use accounting style, which wraps negative numbers in parentheses instead of using a minus sign.

compact : bool = False

A boolean value that allows for compact formatting of numeric values. Values will be scaled and decorated with the appropriate suffixes (e.g., 1230 becomes 1K, and 1230000 becomes 1M). The compact option is False by default.

pattern : str = '{x}'

A formatting pattern that allows for decoration of the formatted value. The formatted value is represented by the {x} (which can be used multiple times, if needed) and all other characters will be interpreted as string literals.

sep_mark : str = ','

The string to use as a separator between groups of digits. For example, using sep_mark="," with a value of 1000 would result in a formatted value of "1,000". This argument is ignored if a locale is supplied (i.e., is not None).

force_sign : bool = False

Should the positive sign be shown for positive values (effectively showing a sign for all values except zero)? If so, use True for this option. The default is False, where only negative numbers will display a minus sign.

locale : str | None = None

An optional locale identifier that can be used for formatting values according the locale’s rules. Examples include "en" for English (United States) and "fr" for French (France).

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.

Adapting output to a specific locale

This formatting method can adapt outputs according to a provided locale value. Examples include "en" for English (United States) and "fr" for French (France). The use of a valid locale ID here means separator marks will be correct for the given locale. Should any value be provided in sep_mark, it will be overridden by the locale’s preferred value.

Note that a locale value provided here will override any global locale setting performed in GT()’s own locale argument (it is settable there as a value received by all other methods that have a locale argument).

Examples

For this example, we’ll use the exibble dataset as the input table. With the fmt_integer() method, we’ll format the num column as integer values having no digit separators (with the use_seps=False option).

from great_tables import GT, exibble

(
    GT(exibble)
    .fmt_integer(columns="num", use_seps=False)
)
