group_rows(kable_input, group_label = NULL, start_row = NULL,
  end_row = NULL, index = NULL,
  label_row_css = "border-bottom: 1px solid;",
  latex_gap_space = "0.3em", escape = TRUE, latex_align = "l",

}
\arguments{
\item{kable_input}{Output of \code{knitr::kable()} with \code{format} specified}

\item{group_label}{A character string for the name of the group}

\item{start_row}{A numeric value that tells the function in which row the
group starts. Note that the counting excludes header rows and other group
labeling rows}

\item{end_row}{A numeric value that tells the function in which row the group
ends.}

\item{index}{A named vector providing the index for robust row-grouping tasks.
Basically, you can use it in the same way as \code{add_header_above()}.}

\item{label_row_css}{A character string for any customized css used for the
labeling row. By default, the labeling row will have a solid black line
underneath. Only useful for HTML documents.}

\item{latex_gap_space}{A character value telling LaTeX how large the gap
between the previous row and the group labeling row. Only useful for LaTeX
documents.}

\item{escape}{A T/F value showing whether special characters should be
escaped.}

\item{latex_align}{Adjust justification of group_label in latex only. Value should be "c" for
centered on row, "r" for right justification, or "l" for left justification. Default
Value is "l"  If using html, the alignment can be set by using the label_row_css
parameter.}

\item{colnum}{A numeric that determines how many columns the text should span.
The default setting will have the text span the entire length.}

\item{bold}{A T/F value to control whether the text should be bolded.}

\item{italic}{A T/F value to control whether the text should to be emphasized.}

\item{hline_before}{A T/F value that addes a horizontal line before the group_row label.  Default
value is False.}

\item{hline_after}{A replicate of \code{hline.after} in xtable. It
addes a hline after the row}

\item{extra_latex_after}{Extra LaTeX text to be added after the row.}
