# Add header column to the left
-An alternative way of grouping rows is being added to `kableExtra` 0.3.0. Unlike `group_rows`, the new function `add_header_left` adopts a similar syntax with `add_header_above`. It allows users to add multiple layers of row groups, which is a limitation of `group_rows`. A limitation of `add_header_left` is that, you can only use it in `booktabs` tables. There is no future plan to extend support to LaTeX table without booktabs because when a new layer of heading columns being added, every `cline` in normal table needs to be changed. Other limitations include incompatible with `group_rows` and a little in-stable `striped` row coloring behavior. If you don't have special need for multiple layers of heading columns or special love to this format, I will recommend you stick with `group_rows`.
