生成的表中的垂直线/边框不连续（R + Latex + Sweave + xtable）

Question

我正在使用R和Sweave创建一个乳胶报告。该表是使用xtable生成的。以下是用于生成表的代码

<<echo=FALSE, results=tex>>=
tabulatedVal <- getStatTableMacro(portfolio, normalizingRow)
createdXTable <- xtable(tabulatedVal, digits = 2)
align(createdXTable) <- "l|l|c|"
rws <- seq(1, nrow(tabulatedVal), by=2)
col <- rep("\\rowcolor{blue!10}", length(rws))
print(createdXTable, booktabs=TRUE, add.to.row=list(pos=as.list(rws), command=col),     include.rownames=FALSE, size="\\small")
@

生成的值很好，但分隔列（以及边框）的垂直线不是连续的。

我试图删除颜色，看起来更好，但垂直线条/边框之间仍有间隙

<<echo=FALSE, results=tex>>=
tabulatedVal <- getStatTableMacro(portfolio, normalizingRow)
createdXTable <- xtable(tabulatedVal, digits = 2)
align(createdXTable) <- "l|l|c|"
rws <- seq(1, nrow(tabulatedVal), by=2)
print(createdXTable, booktabs=TRUE, include.rownames=FALSE, size="\\small")

有关如何解决此问题的想法

修改：按要求提供更完整的示例

\documentclass[xcolor=table,professionalfonts,a4paper,11pt]{article}
\usepackage[margin=1.0in]{geometry}
\usepackage{graphicx}
\usepackage{booktabs}
\usepackage{multicol}
\usepackage[skip=12pt]{caption}
\usepackage{colortbl, xcolor}
\usepackage{helvet}
\usepackage[noae]{Sweave}

\begin{document}

<<echo=FALSE, results=tex>>=

#Colored Table

tabulatedVal <- data.frame(Statistics =c("Annualized Return (%)", "Standard Deviation (%)", "Skewness", "Kurtosis",
                             "Sharpe Ratio", "Maximum Drawdown", "Percent of losing months",
                              "Worst Monthly Return", "Worst Yearly Return"),
                           Value =c(0.09, 6.77, 0.11, 3.18, 1.34, 5.20, 31.84, -4.09, -0.33))
createdXTable <- xtable(tabulatedVal, digits = 2)
align(createdXTable) <- "l|l|c|"
rws <- seq(1, nrow(tabulatedVal), by=2)
col <- rep("\\rowcolor{blue!10}", length(rws))
print(createdXTable, booktabs=TRUE, add.to.row=list(pos=as.list(rws), command=col), include.rownames=FALSE, size="\\small")


#Uncolored Table

createdXTable <- xtable(tabulatedVal, digits = 2)
align(createdXTable) <- "l|l|c|"
rws <- seq(1, nrow(tabulatedVal), by=2)
print(createdXTable, booktabs=TRUE, include.rownames=FALSE, size="\\small")

\end{document}

结果是一样的。

在运行Sweave

之后还添加生成的tex文件

\documentclass[xcolor=table,professionalfonts,a4paper,11pt]{article}
\usepackage[margin=1.0in]{geometry}
\usepackage{graphicx}
\usepackage{booktabs}
\usepackage{multicol}
\usepackage[skip=12pt]{caption}
\usepackage{colortbl, xcolor}
\usepackage{helvet}
\usepackage[noae]{Sweave}

Answer 1

这里的关键是booktabs与垂直线不能很好地配合。您可以切换表中的垂直规则，也可以采用here上描述的here或TeX SE解决方案之一。根据这些问题的评论和答案，共识建议似乎是完全避免纵向规则。

Answer 2

我无法复制问题，但表边框是连续的，并且将包选项保持在最低限度。使用knitr进行编译：

该问题可能与包multicol有关，该问题已在下面说明：

LaTex代码：

\documentclass{article}
\usepackage{geometry}
\usepackage{graphicx}
\usepackage{booktabs}
%\usepackage{multicol}
%\usepackage[skip=12pt]{caption}
\usepackage{colortbl, xcolor}
%\usepackage{helvet}
%\usepackage[noae]{Sweave}
