Starting with version 0.5.0 of qwraps2, the summary_table method has been extended to handle this without building a interaction column.

library(qwraps2)
options(qwraps2_markup = "markdown")

    list("Miles Per Gallon" =

                 list("min" = ~ min(disp),
                      "median" = ~ median(disp),

The headers 0.3, 1.3, … are not that helpful. There are several options for getting better headers. One option would be to get human readable character or factor versions of vs an gear, or to modify the output from summary_table.

colnames(st) <-
  sub("^(\\d).", "VS = \\1, ", sub("\\.(\\d)", " Gear = \\1", colnames(st) ))

st
