26.13 Improvements Using BookTabs
REVIEW The booktabs package for
LaTeX provides additional functionality that we can make use of
with knitr::kable(). To use this be sure to include the
following in the preamble (before the \begin{document} of your
.Rnw file:
# Load the package from the local library into the R session.
\usepackage{booktabs}We can then set booktabs=TRUE to remove the clutter
of the extra lines.
# Use the booktabs option to improve presentation of the table.
ds %>% kable(row.names=FALSE, digits=0, booktabs=TRUE)| Location | MinTemp | MaxTemp | Rainfall | Evaporation |
|---|---|---|---|---|
| Wollongong | 15 | 23 | 0 | NA |
| Williamtown | 22 | 28 | 0 | 6 |
| Mildura | 6 | 20 | 0 | 8 |
| MountGinini | 1 | 8 | 0 | NA |
| SydneyAirport | 22 | 30 | 0 | 5 |
In the following example we notice that with more rows
booktabs=TRUE will add a small gap every 5 rows.
# Display a tale with more observations.
