FR: add the option of naming the column of row.names

[iago-pssjd]

I would like to explicit a name for the column of row.names so I try

d2 = head(mtcars)
kable(d2[, 1:5], col.names = c("car", names(d2[, 1:5])))
Error in dimnames(x) <- dn : 
  length of 'dimnames' [2] not equal to array extent

Maybe, another option would be allow a string for row.names as follows -kable(d2[, 1:5], row.names = "cars")-, so kable would understand it as a TRUE and further naming the column.

Thank you!

I have experienced the same situation and worked around with tibble::rownames_to_column.

d2 = head(mtcars)
d2[1:5] |>
  tibble::rownames_to_column() |>
  kable(col.names = c("car", names(d2[1:5]))

allow a string for row.names

This may be confusing because users would analogize the similar behavior among col.names and row.names.

As documented, kable is a very simple table generator. I think complex steps should come prior to kable when possible.

Should be fixed now. Thanks for the report!
