如何将多个Kable表格以m×n网格展示？以3×2布局为例

直接调用kable(list(t1,t2,t3,t4,t5,t6))会让所有表格横向排列，要实现3行2列的布局，可借助kableExtra包的分组拼接功能，分两种输出场景处理：

HTML输出场景 #

将表格两两分组为一行，每组内的两个表格各占50%宽度，再将三行拼接起来：

library(kableExtra)

# 定义表格
t1 <- mtcars[1:3,]
t2 <- mtcars[4:6,]
t3 <- mtcars[7:9,]
t4 <- mtcars[10:12,]
t5 <- mtcars[13:15,]
t6 <- mtcars[16:18,]

# 构建每行的双表格布局
row1 <- kables(list(kable(t1) %>% kable_styling(), 
                    kable(t2) %>% kable_styling())) %>%
  column_spec(1, width = "50%") %>%
  column_spec(2, width = "50%")

row2 <- kables(list(kable(t3) %>% kable_styling(), 
                    kable(t4) %>% kable_styling())) %>%
  column_spec(1, width = "50%") %>%
  column_spec(2, width = "50%")

row3 <- kables(list(kable(t5) %>% kable_styling(), 
                    kable(t6) %>% kable_styling())) %>%
  column_spec(1, width = "50%") %>%
  column_spec(2, width = "50%")

# 拼接所有行
row1 %>% append_row(row2) %>% append_row(row3)

PDF输出场景 #

借助LaTeX的minipage环境控制表格宽度，每行放置两个表格：

library(kableExtra)

# 定义表格（同上）
t1 <- mtcars[1:3,]
t2 <- mtcars[4:6,]
t3 <- mtcars[7:9,]
t4 <- mtcars[10:12,]
t5 <- mtcars[13:15,]
t6 <- mtcars[16:18,]

# 输出3×2布局
cat("\\begin{minipage}{0.48\\textwidth}\n")
kable(t1) %>% kable_styling(latex_options = "hold_position")
cat("\\end{minipage} \\hfill\n")
cat("\\begin{minipage}{0.48\\textwidth}\n")
kable(t2) %>% kable_styling(latex_options = "hold_position")
cat("\\end{minipage}\n\n")

cat("\\begin{minipage}{0.48\\textwidth}\n")
kable(t3) %>% kable_styling(latex_options = "hold_position")
cat("\\end{minipage} \\hfill\n")
cat("\\begin{minipage}{0.48\\textwidth}\n")
kable(t4) %>% kable_styling(latex_options = "hold_position")
cat("\\end{minipage}\n\n")

cat("\\begin{minipage}{0.48\\textwidth}\n")
kable(t5) %>% kable_styling(latex_options = "hold_position")
cat("\\end{minipage} \\hfill\n")
cat("\\begin{minipage}{0.48\\textwidth}\n")
kable(t6) %>% kable_styling(latex_options = "hold_position")
cat("\\end{minipage}\n")

注意事项 #

• 确保已安装并加载kableExtra包（执行install.packages("kableExtra")完成安装）
• HTML布局依赖kableExtra的kables()和column_spec()函数，PDF布局依赖LaTeX环境支持
