    <p>You need some pre-processing, extra argument passed to <code>print.xtable</code> and some post-processing:</p> <pre><code>my.table &lt;- data.frame(Specifiers=c("","Spec1", "Spec2", "Spec3"), Values1 = c("N=10", 1.03, 1.71, 2.25), Values2 = c("N=20", 1.32, 1.79, 2.43)) colnames(my.table)[1] &lt;- "" # Pre-processing: rotates column names by 45 degrees head = apply(as.array(names(my.table)), 1, function(x) paste("\\rotatebox{45}{", x, "}")) head = paste(head, c(rep("&amp;", length(head)-1), "\\\\\n"), collapse="") latex.tab &lt;- xtable(my.table, caption=c("Stats")) ltable = print(latex.tab, file="", # File is empty, post-processing needed floating.environment='sidewaystable', include.rownames=FALSE, include.colnames=FALSE, # No colnames booktabs=TRUE, latex.environment="center", # Or NULL # Adds some extra-text after the rows specified in pos. # Adds new \midrule and comments old one. # Adds pre-processed names of columns add.to.row=list(pos=as.list(c(0, 0, 1)), command=as.vector(c(head, "%", "\\midrule\n")))) # Post-processing: replaces \begin{center} with \centering ltable = sub("\\begin{center}\n", "\\centering\n", ltable, fixed=TRUE) ltable = sub("\\end{center}\n", "\n", ltable, fixed=TRUE) # Post-processing: adds alternating colours ltable = sub("\\begin{tabular}", "\\rowcolors{2}{gray!25}{white}\n\\begin{tabular}", ltable, fixed=TRUE) # Writes output to the file cat(ltable, file="Summarystats.tex") </code></pre> <p>If you need other tabs environment than <code>tabular</code> you can 1) add new variable:</p> <pre><code>TABULAR = "tabular" </code></pre> <p>2) Pass it's value to <code>print.xtable</code> like this:</p> <pre><code>... tabular.environment=TABULAR, ... </code></pre> <p>3) Change your post-processing for alternating colors:</p> <pre><code>ltable = sub(sprintf("\\begin{%s}", TABULAR), sprintf("\\rowcolors{2}{gray!25}{white}\n\\begin{%s}", TABULAR), ltable, fixed=TRUE) </code></pre> <p>Result:</p> <p><img src="https://i.stack.imgur.com/V9nvU.png" alt="enter image description here"></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
