In my shiny
app I am using datatable
function from DT
library to construct a table and want to align columns on center. I can use formatStyle('column', textAlign = 'center')
but it affects only column body and not the header.
We have to set columnDefs
in the argument option
of the function datatable
.
See example below:
library(DT)
datatable(head(iris),
rownames = FALSE,
options = list(
columnDefs = list(list(className = 'dt-center', targets = 0:4))
)
)
We have to set the target. In the example all the 5 columns are aligned to "center" (targets = 0:4
).
Finally, note that column numbers start from 0, not from 1.
Note: we can use targets="_all"
to apply to all columns regardless of number of columns.
