Column names border only ggtexttable()

[nataliagalant]

Wondering if its possible to/if so how to add a bottom border right under the column names. So nowhere else in the table body, just a horizontal line across the top and bottom of the column name cells for a ggtexttable().

[kassambara]

This feature is now available:

suppressPackageStartupMessages(library("ggpubr"))
# Column names border only
ggtexttable(head(iris), rows = NULL, theme = ttheme("blank")) %>%
  tab_add_hline(at.row = 1:2, row.side = "top", linewidth = 2)
