sprinkle_pad: Sprinkle the Padding of a Cell

Description

Padding for HTML tables indicates how many pixels should be placed between the cell's content and the outside border.

Usage

sprinkle_pad(
  x,
  rows = NULL,
  cols = NULL,
  pad = 0,
  part = c("body", "head", "foot", "interfoot", "table"),
  fixed = FALSE,
  recycle = c("none", "rows", "cols", "columns"),
  ...
)
# S3 method for default
sprinkle_pad(
  x,
  rows = NULL,
  cols = NULL,
  pad = 0,
  part = c("body", "head", "foot", "interfoot", "table"),
  fixed = FALSE,
  recycle = c("none", "rows", "cols", "columns"),
  ...
)
# S3 method for dust_list
sprinkle_pad(
  x,
  rows = NULL,
  cols = NULL,
  pad = 0,
  part = c("body", "head", "foot", "interfoot", "table"),
  fixed = FALSE,
  recycle = c("none", "rows", "cols", "columns"),
  ...
)

Arguments

x: An object of class dust
rows: Either a numeric vector of rows in the tabular object to be modified or an object of class call. When a call, generated by quote(expression), the expression resolves to a logical vector the same length as the number of rows in the table. Sprinkles are applied to where the expression resolves to TRUE.
cols: Either a numeric vector of columns in the tabular object to be modified, or a character vector of column names. A mixture of character and numeric indices is permissible.
pad: numeric(1) A character string giving a color for the background of the chosen cells.
part: A character string denoting which part of the table to modify.
fixed: logical(1) indicating if the values in rows and cols should be read as fixed coordinate pairs. By default, sprinkles are applied at the intersection of rows and cols, meaning that the arguments do not have to share the same length. When fixed = TRUE, they must share the same length.
recycle: A character one that determines how sprinkles are managed when the sprinkle input doesn't match the length of the region to be sprinkled. By default, recycling is turned off. Recycling may be performed across rows first (left to right, top to bottom), or down columns first (top to bottom, left to right).
...: Additional arguments to pass to other methods. Currently ignored.

Functional Requirements

Correctly reassigns the appropriate elements pad column in the table part.
Casts an error if x is not a dust object.
Casts an error if pad is not a numeric(1)
Casts an error if part is not one of "body", "head", "foot", or "interfoot"
Casts an error if fixed is not a logical(1)
Casts an error if recycle is not one of "none", "rows", or "cols"
Cast an error if recycle = "none" and pad does not have length 1.

The functional behavior of the fixed and recycle arguments is not tested for this function. It is tested and validated in the tests for index_to_sprinkle.

Details

Colors may be a dvips color name, or in the rgb(R, G, B), rgba(R, G, B, A), #RRGGBB, or #RRGGBBAA formats.

This sprinkle is ignored in console and markdown outputs. HTML output will accept any of the color formats and recognize transparency. LaTeX output will accept any of the color formats but ignore transparency.
