Two font faces in grid.tables

Question

I have created a grid.table object to display a dataframe in PowerBi, below there is my code:

library(reshape)
library(gridExtra)
library(grid)
mydf <- data.frame(id = c(1:5), value = c("A","B","C","D","E"))
mytheme <- ttheme_default(base_size = 10,
                          core=list(fg_params=list(hjust=0, x=0.01),
                                    bg_params=list(fill=c("white", "lightgrey"))))

grid.table(mydf,cols = NULL, theme = mytheme, rows = NULL)

and this is my output:

I would like to style the font of the output so that only the first column has the font in bold, does anyone knows how to achive this?

Thanks

grid.table() is just a wrapper for grid.draw(tableGrob(...))

You can get your desired results with some Grob surgery:

library(grid)
library(gridExtra)

mydf <- data.frame(id = c(1:5), value = c("A","B","C","D","E"))

mytheme <- ttheme_default(base_size = 10, 
                          core = list(fg_params=list(hjust=0, x=0.01),
                                      bg_params=list(fill=c("white", "lightgrey"))))

Make the tableGrob:

tg <- tableGrob(mydf, cols = NULL, theme = mytheme, rows = NULL)

Edit the tableGrob (column 1 is first 5 slots):

for (i in 1:5) {
  tg$grobs[[i]] <- editGrob(tg$grobs[[i]], gp=gpar(fontface="bold"))
}

I like to use a new page for examples , but you can remove it since grid.table() doesn't use it either:

grid.newpage()
grid.draw(tg)
