)By default this function outputs (see: cat) the result. If you would want to catch the result instead, then call pandoc.table.return instead.
data frame, matrix or table
caption (string) to be shown under the table
passed to format. Can be a vector specifying values for each column (has to be the same length as number of columns).
passed to format
passed to format
passed to round. Can be a vector specifying values for each column (has to be the same length as number of columns). Values for non-numeric columns will be disregarded.
string to replace missing values
defines alignment in cells passed to format. Can be left, right or centre, which latter can be also spelled as center. Defaults to centre. Can be abbreviated to a string consisting of the letters l, c and r (e.g. 'lcr' instead of c('left', 'centre', 'right').
which Pandoc style to use: simple, multiline, grid or rmarkdown
where to split wide tables to separate tables. The default value (80) suggests the conventional number of characters used in a line, feel free to change (e.g. to Inf to disable this feature) if you are not using a VT100 terminal any more :)
where to split cells' text with line breaks. Default to 30, to disable set to Inf. Can be also supplied as a vector, for each cell separately (if length(split.cells) == number of columns + 1, then first value in split.cells if for row names, and others are for columns). Supports relative (percentage) parameters in combination with split.tables.
to show or remove trailing zeros in numbers on a column basis width
(default: FALSE) if to keep or remove line breaks from cells in a table
(default: FALSE) if output should be in plain ascii (without markdown markup) or not
boolean (default: FALSE) if try to use hyphening when splitting large cells according to table.split.cells. Requires sylly.
if FALSE, row names are suppressed. A character vector of row names can also be specified here. By default, row names are included if rownames(t) is neither
NULL nor identical to 1:nrow(x)
a character vector of column names to be used in the table
boolean (default: TRUE) if row names should be highlighted

unsupported extra arguments directly placed into /dev/null
This function takes any tabular data as its first argument and will try to make it pretty like: rounding and applying digits and custom decimal.mark to numbers, auto-recognizing if row names should be included, setting alignment of cells and dropping trailing zeros by default.
pandoc.table also tries to split large cells with line breaks or even the whole table to separate parts on demand. Other arguments lets the use to highlight some rows/cells/cells in the table with italic or bold text style.
For more details please see the parameters above and passed arguments of panderOptions.
