在应用中降价我经常在这里找到有关“LaTeX”和“pandoc”的答案TeX Stackchange. 因此，我想在这里重复一下我的我在 stackoverflow 上问过的问题希望找到使用 pandoc 通过 LaTeX 转换为 PDF 时以下问题的解决方案：
我面临的问题是，Rtexreg()似乎无法在表格下方的注释中换行。此外，模型之间的边距没有像现在这样均匀延伸，从而htmlreg()产生干净的结果。手动换行（如\n或 HTML 标签）无法与“texreg”配合使用。部分MichaelChirico 的解决方案但是必须改变函数texreg()，但当我们并排处理多个模型时，该方法似乎不尊重这种情况。
以下是我使用的代码：
---
title: "Untitled"
author: "jaySf"
date: "13 Juni 2017"
output:
pdf_document: default
html_document: default
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
```{r results="asis"}
library(car)
lm1 <- lm(prestige ~ income, data=Duncan)
lm2 <- lm(prestige ~ education, data=Duncan)
lm3 <- lm(prestige ~ income + education, data=Duncan)
library(texreg)
texreg(list(lm1, lm2, lm3), custom.note = "Lorem ipsum dolor sit amet, <br>consetetur sadipscing
elitr, sed diam. %stars.") # for pdf output
htmlreg(list(lm1, lm2, lm3), custom.note = "Lorem ipsum dolor sit amet, <br>consetetur sadipscing
elitr, sed diam. %stars.") # for html output
```
输出结果如下：
有人知道吗？任何帮助都值得感激。

请注意，您的自定义注释以 结尾\multicolumn，因此您不能使用换行符命令作为\par或\\，但您可以使用\parbox：
custom.note = "\\parbox{\\linewidth}{Lorem ipsum dolor sit amet,
\\\\ consetetur sadipscing elitr, sed diam. %stars.}"
您还可以允许在较窄的范围内自动换行\parbox，从而避免最后一列的宽度过大：
custom.note = "\\parbox{.4\\linewidth}{Lorem ipsum dolor sit amet,
consetetur sadipscing elitr, sed diam. %stars.}"
