ht_gap controls the space between heatmaps. The value can be a single unit or a vector of units.

ht1 = Heatmap(mat1, name = "rnorm", col = col_rnorm)
ht2 = Heatmap(mat2, name = "runif", col = col_runif)
ht3 = Heatmap(le, name = "letters", col = col_letters)
ht_list = ht1 + ht2 + ht3
draw(ht_list, ht_gap = unit(1, "cm"))

draw(ht_list, ht_gap = unit(c(3, 10), "mm"))
