let's assume column carb cluster column. see have 4 different clusters put output of 2 columns (starting first one) on separate page in pdf.

first page should like:

  1. datsun 710 22.8
  2. hornet 4 drive 21.4
  3. valiant 18.1

second page should like:

  1. hornet sportabout 18.7
  2. merc 240d 24.4
  3. merc 230 22.8

third page should like:

  1. merc 450se 16.4

and believe know how output of last page should like. can me ? data frame contains in total around 250 clusters.

grid.newpage() forces each table appear on new page,

pdf("multipage.pdf") lapply(split(mtcars, mtcars$carb), function(d) {   grid::grid.newpage()   gridextra::grid.table(d)   }   ) dev.off()
