#' Table of values for the constants d2, d3 and c4.
#' 
#' This function is used to build a table of values for the constants d2, d3
#' and c4 for sucessive values of sample size n.
#' 
#' It builds a table in matrix form with 3 columns (one for each constant) and
#' one row for each value of n from 2 to a specified value.
#' 
#' @param n The maximum size.
#' @return Return the values of these three constants.
