R:Rmarkdown中的2列布局，带选项卡集

我正在尝试使用CSS将sapce分成两部分的两列布局。但是，{.tabset}命令不起作用。我尝试了多种组合，但没有任何帮助

---
title: "2 Column layout with tabs"
output:
  html_document:
    css: style.css
---

<div class = "col-leftmid">

# A {.tabset}

## abc

</div>

<div class = "col-rightmid">

# B {.tabset}

## xyz

</div>

我想我已经找到了解决办法，而且目前还有效。我只需要在tabset调用旁边提到“col leftmid”/“col righmid”

title: "2 Column layout with tabs"
output:
  html_document:
    css: style.css
---

# A {.tabset .col-leftmid}

## abc


# B {.tabset .col-rightmid}

## xyz

## mno
