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

Question

我正在使用 R 和 Sweave 在乳胶中创建报告。 该表是使用 xtable 生成的。 以下是用于生成表格的代码

<<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")
@

这些值生成良好，但分隔列（以及边框）的垂直线不连续。

我试图删除颜色，它看起来更好，但垂直线/边框之间仍然有间隙

<<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")

关于如何解决这个问题的任何想法

编辑：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。

运行 Sweave 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不能很好地与垂直线配合。 您可以从表格中的垂直规则中切换出来，或者采用此处或此处在TeX SE上描述的解决方案之一。 根据对这些问题的评论和回答，共识建议似乎是完全避免垂直规则。

Answer 2

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

该问题可能与下面已注释掉的包multicol有关：

乳胶代码：

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