Removed in 2.0.0. Use tab_html(), which renders any table – a tabxplor_tab or a plain
data.frame – through the shared exporter prep, with colours, tooltips and spanning headers.
kable_tabxplor_style() predated tab_html() and never shared its machinery: it found total
rows and columns by matching the literal strings "Total" / "Ensemble", so it was hardcoded to
English and French. Nothing in the package ever called it.
