I already created many .PDF files via ".R" -> (roxygen2) ".Rd" -> (R CMD check mypackage) ".PDF".
Now, I wanted to add a table template in .PDF file of the package (mypackage-manual.pdf):
Table: ADF Statistics of the Raw Variables
---------------------------------------------------------------------
var type inc levelt Pc c Pt t prob omlo type inc 1stDifft Pc c Pt t prob omlo intorder
----------------------------------------------------------------------
1 Var1 dt dt
2 Var1 d d
3 Var1 - -
4 Var2 dt dt
5 Var2 d d
6 Var2 - -
------------------------------------------------------------------------
What I did:
1. I pressed to spacebar lots of times to allocate enough spaces so that "dt"/"d"/"-" are placed under the type column.
But, upon [".R" -> (roxygen2) ".Rd" -> (R CMD check package) ".PDF"] process, these spaces did not appear as if I did not pressed spacebar at all!
2. I inserted lots of "\quad" tags to produce enough spaces in the preamble of ".R" file:
#' Table: ADF Statistics of the Raw Variables \cr
#' -------------------------------------------------- \cr
#' var type inc levelt Pc c Pt t prob omlo type inc 1stDifft Pc c Pt t prob omlo intorder \cr
#' ------------------------------------------------------------------ \cr
#' 1 Var1 dt\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad dt \cr
#' 2 Var1 d \quad\quad\quad\quad\quad\quad\quad\quad\quad\quad d \cr
#' 3 Var1 - \quad\quad\quad\quad\quad\quad\quad\quad\quad\quad - \cr
#' 4 Var2 dt \quad\quad\quad\quad\quad\quad\quad\quad\quad\quad dt \cr
#' 5 Var2 d \quad\quad\quad\quad\quad\quad\quad\quad\quad\quad d \cr
#' 6 Var2 - \quad\quad\quad\quad\quad\quad\quad\quad\quad\quad - \cr
#' -------------------------------------------------------------------- \cr
But, upon [".R" -> (roxygen2) ".Rd" -> (R CMD check package) ".PDF"] process, all of these "\quad" tags were not processed, and all of them was printed in the resultant .PDF as if they are text, not tags:
Table: ADF Statistics of the Raw Variables

var type inc levelt Pc c Pt t prob omlo type inc 1stDifft Pc c Pt t prob omlo intorder
------------------------------------------------------------------
1 Var1 dt\quad\quad\quad\quad\quad\quad\quad\quad dt
2 Var1 d \quad\quad\quad\quad\quad\quad\quad\quad d
3 Var1 - \quad\quad\quad\quad\quad\quad\quad\quad -
4 Var2 dt \quad\quad\quad\quad\quad\quad\quad\quad dt
5 Var2 d \quad\quad\quad\quad\quad\quad\quad\quad d
6 Var2 - \quad\quad\quad\quad\quad\quad\quad\quad -
--------------------------------------------------------------------
As a newbee to latex, I could not achieve to put enough spaces. Also, I am not sure whether "being a newbee to latex" and "peculiar code required by roxygen2" is my deficiency. Any help would be greatly appreciated.
3. Thomas' solution (as far as I can apply):
#' \tabular{ccccccccccccccccccccc}{
#' . \tab var \tab type \tab inc \tab levelt \tab Pc \tab c \tab Pt \tab t \tab prob \tab omlo \tab type \tab inc \tab 1stDifft \tab Pc \tab c \tab Pt \tab t \tab prob \tab omlo \tab intorder \cr
#' 1 \tab Var1 \tab dt \tab \tab \tab \tab \tab \tab \tab \tab \tab dt \tab \tab \tab \tab \tab \tab \tab \tab \tab \cr
#' 2 \tab Var1 \tab d \tab \tab \tab \tab \tab \tab \tab \tab \tab d \tab \tab \tab \tab \tab \tab \tab \tab \tab \cr
#' 3 \tab Var1 \tab - \tab \tab \tab \tab \tab \tab \tab \tab \tab - \tab \tab \tab \tab \tab \tab \tab \tab \tab \cr
#' 4 \tab Var2 \tab dt \tab \tab \tab \tab \tab \tab \tab \tab \tab dt \tab \tab \tab \tab \tab \tab \tab \tab \tab \cr
#' 5 \tab Var2 \tab d \tab \tab \tab \tab \tab \tab \tab \tab \tab d \tab \tab \tab \tab \tab \tab \tab \tab \tab \cr
#' 6 \tab Var2 \tab - \tab \tab \tab \tab \tab \tab \tab \tab \tab - \tab \tab \tab \tab \tab \tab \tab \tab \tab
#' }
did this:
. var type inc levelt Pc c Pt t prob omlo type inc 1stDifft Pc c Pt t prob oml
1 Var1 dt dt
2 Var1 d d
3 Var1 - -
4 Var2 dt dt
5 Var2 d d
6 Var2 - -
The column names did not fit into right side of .PDF at the end, and "o intorder" was not shown in the resultant .PDF.

I tried xcolor package and its derivatives to make dots appear white, but it failed.
