Pdf Markdown table vertical line

Question

Is it possible to draw a vertical line between columns in pdf Markdown table? I am going to separate each column and make a table like this:

Answer 1

For the sake of having a reproducible answer available:

library(xtable)
data(tli)
tli.table <- xtable(tli[1:10, ])
align(tli.table) <- "|rrl|l|lr|"
tli.table

Of course, for more details do check out the xtable document in George Dontas' response.

Answer 2

if you are using the xtable package, see 5.2 Column alignment here
