如何在officedown中并排放置带独立标题的两张图表？

当前图表为上下排列：

期望实现的效果：

原代码中图表默认上下排列，HTML环境的横向排版方案不适用于officedown生成docx的场景，需使用officedown专属的列布局语法实现需求。

修改后的代码 #

---
title: "Untitled"
author: ""
date: "`r Sys.Date()`"
output:
  officedown::rdocx_document

# Heading 1

### 核心说明
- 用`::: columns`定义多列容器，内部每个`::: column`对应一列，默认两列宽度均等
- 每个图表代码块单独包裹在`::: column`中，生成后会横向排列，且各自保留独立的`fig.cap`标题
- 无需调整图表的尺寸参数，原有`fig.width`和`fig.height`可直接适配列布局
