This is how a default reactable table looks like:
To get started with reactable, you can install it
directly from CRAN using the install.packages function:
The reactable package provides one main function:
reactable(). It takes a data frame as input and returns an
interactive table.
This is how the table above was produced:
You can enable searching by setting the searchable
argument to TRUE.
Example:
You can enable filtering by setting the filterable
argument to TRUE.
Example:
You can enable grouping and aggregating by setting
the groupBy argument to the name of a column and by adding
the aggregate argument in each column definition.
Example:
table <- reactable(iris,
groupBy = "Species", # Group by the Species column
columns = list(
Sepal.Length = colDef(aggregate = "max"), # max value
Sepal.Width = colDef(aggregate = "mean", format = colFormat(digits = 1)), # mean value
Petal.Length = colDef(aggregate = "unique"), # unique values
Petal.Width = colDef(aggregate = "min") # min value
)
)
tableYou can customize the appearance of the table by setting the
theme argument to a reactableTheme object. You
can also use the striped or highlight
arguments to add stripes or highlight
the hovered row.
Example:
table <- reactable(
iris[1:30, ],
striped = TRUE,
highlight = TRUE,
theme = reactableTheme(
borderColor = "#dfe2e5",
stripedColor = "#f6f8fa",
highlightColor = "red",
cellPadding = "8px 12px",
style = list(fontFamily = "-apple-system, BlinkMacSystemFont, Segoe UI, Helvetica, Arial, sans-serif"),
searchInputStyle = list(width = "100%")
))
