Column definitions

Use colDef() to customize the columns in a table.

colDef(
  name = NULL,
  aggregate = NULL,
  sortable = NULL,
  resizable = NULL,
  filterable = NULL,
  show = NULL,
  defaultSortOrder = NULL,
  sortNALast = FALSE,
  format = NULL,
  cell = NULL,
  aggregated = NULL,
  header = NULL,
  footer = NULL,
  details = NULL,
  html = FALSE,
  na = "",
  minWidth = NULL,
  maxWidth = NULL,
  width = NULL,
  align = NULL,
  class = NULL,
  style = NULL,
  headerClass = NULL,
  headerStyle = NULL,
  footerClass = NULL,
  footerStyle = NULL
)

Arguments

name	Column header name.
aggregate	Aggregate function to use when rows are grouped. The name of a built-in aggregate function or a custom JS() aggregate function. Built-in aggregate functions are: "mean", "sum", "max", "min", "median", "count", "unique", and "frequency". To enable row grouping, use the groupBy argument in reactable().
sortable	Enable sorting? Overrides the table option.
resizable	Enable column resizing? Overrides the table option.
filterable	Enable column filtering? Overrides the table option.
show	Show the column? Overrides the table option.
defaultSortOrder	Default sort order. Either "asc" for ascending order or "desc" for descending order. Overrides the table option.
sortNALast	Always sort missing values (NA or NaN) last?
format	Column formatting options. A colFormat() object to format all cells, or a named list of colFormat() objects to format standard cells ("cell") and aggregated cells ("aggregated") separately.
cell	Custom cell renderer. An R function that takes the cell value, row index, and column name as arguments, or a JS() function that takes a cell info object as an argument.
aggregated	Custom aggregated cell renderer. A JS() function that takes a cell info object as an argument.
header	Custom header renderer. An R function that takes the header value and column name as arguments, or a JS() function that takes a column info object as an argument.
footer	Footer content or render function. Render functions can be an R function that takes two arguments, the column values and column name, or a JS() function that takes a column info object as an argument.
details	Additional content to display when expanding a row. An R function that takes a row index argument or a JS() function that takes a row info object as an argument. Cannot be used on a grouping column.
html	Render content as HTML? Raw HTML strings are escaped by default.
na	String to display for missing values (i.e. NA or NaN). By default, missing values are displayed as blank cells.
minWidth	Minimum width of the column in pixels. Defaults to 100.
maxWidth	Maximum width of the column in pixels.
width	Fixed width of the column in pixels. Overrides minWidth and maxWidth.
align	Column alignment. One of "left", "right", "center".
class	Additional CSS classes to apply to cells. Can also be an R function that takes the cell value, row index, and column name as arguments, or a JS() function that takes a row info object, column info object, and table state object as arguments. Note that R functions cannot apply classes to aggregated cells.
style	Inline styles to apply to cells. A named list or character string. Can also be an R function that takes the cell value and row index as arguments, or a JS() function that takes a row info object, column info object, and table state object as arguments. Note that R functions cannot apply styles to aggregated cells. If style is a named list, property names should be camelCased.
headerClass	Additional CSS classes to apply to the header.
headerStyle	Inline styles to apply to the header. A named list or character string. Note that if headerStyle is a named list, property names should be camelCased.
footerClass	Additional CSS classes to apply to the footer.
footerStyle	Inline styles to apply to the footer. A named list or character string. Note that if footerStyle is a named list, property names should be camelCased.

Value

A column definition object that can be used to customize columns in reactable().

Examples

reactable(
  iris,
  columns = list(
    Sepal.Length = colDef(name = "Sepal Length"),
    Sepal.Width = colDef(filterable = TRUE),
    Petal.Length = colDef(show = FALSE),
    Petal.Width = colDef(defaultSortOrder = "desc")
  )
)
