how to show the title of a table with tableGrob?

Question

Consider this example

library(gridExtra)
library(grid)

d1 <- head(iris[,1:3]) %>% as_tibble()
d2 <- head(iris[,2:5]) %>% as_tibble()

grid.arrange(tableGrob(d1),
             tableGrob(d2))

This is really nice but I am missing the titles of the dataframes! How can I add them to the picture automatically?

Thanks!

You can use ggplot,

library(ggplot2)

dd1 <- ggplot() + annotation_custom(tableGrob(d1)) + labs(title = 'd1')
dd2 <- ggplot() + annotation_custom(tableGrob(d2)) + labs(title = 'd2')
grid.arrange(dd1, dd2, nrow = 2)
