And similar for `\midrule` and `\bottomrule`.
This facilitates redefining `\toprule`, `\midrule`, and `\bottomrule`
without needing to gobble the ()s.
Closes#8223.
The writer uses features from the longtable package to define the table
foot. Furthermore, the table's bottom rule is now part of the foot,
where it previously was given as part of the body.
These commands take optional arguments with () and [],
which can lead to problems if the content of the table
cell begins with these characters.
Closes#8001.
In 2.11.3 we started adding `\addlinespace`, which produced less
dense tables. This wasn't an intentional change; I misunderstood
a comment in the discussion leading up to the change. This commit
restores the earlier default table appearance.
Note that if you want a less dense table, you can use something like
`\def\arraystretch{1.5}` in your header.
Closes#6996.
+ Remove the `\strut` that was added at the end of minipage
environments in cells.
+ Replace `\tabularnewline` with `\\ \addlinespace`.
Closes#6842, closes#6860.
Note that if the table has a first page header and a
continuation page header, the notes will appear only
on the first occurrence of the header.
Closes#2378.
