Column formatting options

Use colFormat() to add data formatting to a column.

colFormat(
  prefix = NULL,
  suffix = NULL,
  digits = NULL,
  separators = FALSE,
  percent = FALSE,
  currency = NULL,
  datetime = FALSE,
  date = FALSE,
  time = FALSE,
  hour12 = NULL,
  locales = NULL
)

Arguments

prefix

Prefix string.

suffix

Suffix string.

digits

Number of decimal digits to use for numbers.

separators

Whether to use grouping separators for numbers, such as thousands separators or thousand/lakh/crore separators. The format is locale-dependent.

percent

Format number as a percentage? The format is locale-dependent.

currency

Currency format. An ISO 4217 currency code such as "USD" for the US dollar, "EUR" for the euro, or "CNY" for the Chinese RMB. The format is locale-dependent.

datetime

Format as a locale-dependent date-time?

date

Format as a locale-dependent date?

time

Format as a locale-dependent time?

hour12

Whether to use 12-hour time (TRUE) or 24-hour time (FALSE). The default time convention is locale-dependent.

locales

Locales to use for number, date, time, and currency formatting. A character vector of BCP 47 language tags, such as "en-US" for English (United States), "hi" for Hindi, or "sv-SE" for Swedish (Sweden). Defaults to the locale of the user's browser.

Multiple locales may be specified to provide a fallback language in case a locale is unsupported. When multiple locales are specified, the first supported locale will be used.

See a list of common BCP 47 language tags for reference.

Value

A column format object that can be used to customize data formatting in colDef().

See also

Custom cell rendering in colDef() to customize data formatting beyond what the built-in formatters provide.
