Any idea how to adjust the font size of a tableGrob? I am using gridExtra 2.0.0, which seem to be very different previous version 0.9.3.

g <- tableGrob(mtcars)
grid.arrange(g)

enter image description here

I am looking to adjust the font size of the text in the table, header, and rowname as well.

You can do this via themes:

mytheme <- gridExtra::ttheme_default(
    core = list(fg_params=list(cex = 2.0)),
    colhead = list(fg_params=list(cex = 1.0)),
    rowhead = list(fg_params=list(cex = 1.0)))

myt <- gridExtra::tableGrob(mtcars[1:5, 1:5], theme = mytheme)

grid.draw(myt)

There are a number of other examples in browseVignettes("gridExtra") -- look at the tableGrob examples. A great deal of control is possible.
