xlr_table() is designed to work with dplyr verbs by default. This is so you
mutate, summarise, arrange etc. your data without losing your xlr_table
information. Particularly if you have used build_table first on your data,
which outputs data as a xlr_table.
The list of currently supported dplyrs verbs are: arrange, distinct, filter,
mutate, relocate, rename, rename_with, rowwise, select, slice,
slice_head, slice_max, slice_min, slice_sample, slice_tail, summarise.
