+\description{
+When you create a summary table for either model or basic
+summary stats in R, you usually end up having column names in the form of
+"a_mean", "a_sd", "b_mean" and "b_sd". This function streamlines the process
+of renaming these column names and adding extra header rows using
+\code{add_header_above}.
