Column definitions

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

colDef(
  name = NULL,
  aggregate = NULL,
  sortable = NULL,
  resizable = NULL,
  filterable = NULL,
  show = TRUE,
  defaultSortOrder = NULL,
  sortNALast = FALSE,
  format = NULL,
  cell = NULL,
  grouped = NULL,
  aggregated = NULL,
  header = NULL,
  footer = NULL,
  details = NULL,
  html = FALSE,
  na = "",
  rowHeader = FALSE,
  minWidth = 100,
  maxWidth = NULL,
  width = NULL,
  align = NULL,
  vAlign = NULL,
  headerVAlign = NULL,
  sticky = 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?
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 and table state object as arguments.
grouped	Custom grouped cell renderer. A JS() function that takes a cell info object and table state object as arguments.
aggregated	Custom aggregated cell renderer. A JS() function that takes a cell info object and table state object as arguments.
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 and table state object as arguments.
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 and table state object as arguments.
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 and table state object as arguments. Cannot be used on a groupBy 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.
rowHeader	Mark up cells in this column as row headers? Set this to TRUE to help users navigate the table using assistive technologies. When cells are marked up as row headers, assistive technologies will read them aloud while navigating through cells in the table. Cells in the row names column are automatically marked up as row headers.
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	Horizontal alignment of content in the column. One of "left", "right", "center". By default, all numbers are right-aligned, while all other content is left-aligned.
vAlign	Vertical alignment of content in data cells. One of "top" (the default), "center", "bottom".
headerVAlign	Vertical alignment of content in header cells. One of "top" (the default), "center", "bottom".
sticky	Make the column sticky when scrolling horizontally? Either "left" or "right" to make the column stick to the left or right side. If a sticky column is in a column group, all columns in the group will automatically be made sticky, including the column group header.
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")
  )
)
