Question

我正在使用kable（）函数在Rmd knit pdf文档中输出表格。然而，我遇到了一个问题。当我编织pdf时，它输出的表格因宽度过大而最终被裁剪。请参阅下面的模拟代码，以Rmd knit pdf运行。如您所见，缺少列：

```{r, echo=FALSE}
require(knitr)
col1 <- c("City", "Abidjan","Accra","Amman")
col2 <- c("Optimized HDH","217","281","26398")
col3 <- c("Standard HDH","0","0","37056")
col4 <- c("Heating Demand [W/(°C x Capita)]", "0.0","0.0","28.3")
col5 <- c("Heating Energy [kWh/(capita x yr)]","0","0","469.68")
col6 <- c("Threshold Temperature","23.3","24","17.6")
col7 <- c("Optimized CDH","31781","25264","32198")
col8 <- c("Standard CDH", "59398","58895","22059")
col9 <- c("Cooling Demand [W/(°C x capita)]", "1.67", "2.83", "45.72")
col10 <- c("Cooling Energy [kWh/(capita x yr)]", "53", "143.56", "1256.62")
tble <- data.frame(col1, col2, col3, col4, col5, col6, col7, col8, col9, col10)

colnames(tble) <- tble[1,]
tble <- tble[2:4,]
````

```{r, results='asis'}
# kable(tble)
```


|City    |Optimized HDH |Standard HDH |Heating Demand [W/(°C x Capita)] |Heating Energy [kWh/(capita x yr)] |Threshold Temperature |Optimized CDH |Standard CDH |Cooling Demand [W/(°C x capita)] |Cooling Energy [kWh/(capita x yr)] |
|:-------|:-------------|:------------|:--------------------------------|:----------------------------------|:---------------------|:-------------|:------------|:--------------------------------|:----------------------------------|
|Abidjan |217           |0            |0.0                              |0                                  |23.3                  |31781         |59398        |1.67                             |53                                 |
|Accra   |281           |0            |0.0                              |0                                  |24                    |25264         |58895        |2.83                             |143.56                             |
|Amman   |26398         |37056        |28.3                             |469.68                             |17.6                  |32198         |22059        |45.72                            |1256.62                            |

你知道如何避免这种情况吗？也许kable（）中的输入要求重新调整表的大小以适应1页？我累了谷歌搜索和帮助，但没有找到任何有用的信息。

另一个问题：有没有办法让列名超过2行，而不是1？我的问题是colnames太长了。

非常感谢！

有很多选项可以在单元格中拆分文本，或者如果pander太宽则拆分表格，例如：

> pander(tble, split.cells = 20, split.table = Inf)

 **3**   Accra        281             0                0.0                   0                24            25264          58895             2.83                143.56        

 **4**   Amman       26398          37056             28.3                469.68             17.6           32198          22059             45.72               1256.62

请注意style=rmarkdown不支持这一点，因为管道表does not support换行符。使用pander的默认多行样式pandoc。
