\
footnote
command doesn’t work in tables;
the table traps the footnotes and they can’t escape to the bottom of
the page. As a result, you get footnote marks in the table, and
nothing else.
This accords with common typographic advice: footnotes and tables are
reckoned not to mix.
The solution, if you accept the advice, is to use “table notes”.
The package threeparttable provides table notes, and
threeparttablex additionally supports them in
longtable
s. Threeparttable works happily in
ordinary text, or within a table
float.
The ctable package extends the model of
threeparttable, and also uses the ideas of the
booktabs package. The \
ctable
command does the complete
job of setting the table, placing the caption, and defining the
notes. The “table” may consist of diagrams, and a parameter in
\
ctable
’s optional argument makes the float that is created a
“figure” rather than a “table”.
If you really want “real” footnotes in tables, despite the expert
advice, you can:
\
footnotemark
to position the little marker
appropriately, and then put in \
footnotetext
commands to fill in
the text once you’ve closed the tabular
environment.
This is described in Lamport’s book, but it gets messy if there’s
more than one footnote.
minipage
. Footnotes in the
table then “work”, in the minipage
’s style, with no
extra effort. (This is, in effect, somewhat like table notes, but
the typeset appearance isn’t designed for the job.)
tabular
environment, but they do allow
footnotes.
savenotes
which collects all footnotes and emits them
at the end of the environment; thus if you put your
tabular
environment inside the environment, the
footnotes will appear as needed. Alternatively, you may use
\
makesavenoteenv{tabular}
in the preamble of your
document, and tables will all behave as if they were inside a
savenotes
environment.
