fmt_markdown

Format Markdown text

Description

Any Markdown-formatted text in the incoming cells will be transformed to the appropriate output type during render when using fmt_markdown().

Usage

fmt_markdown(data, columns, rows = NULL)

Arguments

`data`	A table object that is created using the `gt()` function.
`columns`	The columns to format. Can either be a series of column names provided in `vars()`, a vector of column indices, or a helper function focused on selections. The select helper functions are: `starts_with()`, `ends_with()`, `contains()`, `matches()`, `one_of()`, and `everything()`.
`rows`	Optional rows to format. Not providing any value results in all rows in `columns` being formatted. Can either be a vector of row captions provided `c()`, a vector of row indices, or a helper function focused on selections. The select helper functions are: `starts_with()`, `ends_with()`, `contains()`, `matches()`, `one_of()`, and `everything()`. We can also use expressions to filter down to the rows we need (e.g., `[colname_1] > 100 & [colname_2] < 50`).

Details

Targeting of values is done through columns and additionally by rows (if nothing is provided for rows then entire columns are selected). A number of helper functions exist to make targeting more effective. Conditional formatting is possible by providing a conditional expression to the rows argument. See the Arguments section for more information on this.

Value

An object of class gt_tbl.

# Create a few Markdown-based

### This is Markdown.

Markdown’s syntax is comprised entirely of
punctuation characters, which punctuation
characters have been carefully chosen so as
to look like what they mean... assuming
you’ve ever used email.
"

text_1b <- "
Info on Markdown syntax can be found
[here](https://daringfireball.net/projects/markdown/).

text_2a <- "
The **gt** package has these datasets:

 - `countrypops`
 - `sza`
 - `gtcars`
 - `sp500`
 - `pizzaplace`
 - `exibble`
"

text_2b <- "

# Arrange the text snippets as a tibble
# using the `dplyr::tribble()` function;
# then, create a gt table and format
# all columns with `fmt_markdown()`
tab_1 <-
  dplyr::tribble(
    ~Markdown, ~md,
    text_1a,   text_2a,
    text_1b,   text_2b,
  ) %>%
    gt() %>%
    fmt_markdown(columns = TRUE) %>%
    tab_options(table.width = px(400))
