Footnote in tabular

A-README.md

Resource for answer in https://tex.stackexchange.com/questions/109467/footnote-in-tabular-environment .

Packages to be tested:

• footnote credit to https://tex.stackexchange.com/a/109471/250119
• footnotehyper package --- direct replacement for footnote package.
• tablefootnote credit to https://tex.stackexchange.com/a/35327/250119 or https://tex.stackexchange.com/a/35328/250119 or https://tex.stackexchange.com/a/35327/250119
• longtable package. (it has native footnote support. As mentioned in the documentation, \footnote will not work in the head or foot sections of the table.)
• ftnxtra package credit to https://tex.stackexchange.com/a/35276/250119
• threeparttable package credit to https://tex.stackexchange.com/a/327385/250119 or https://tex.stackexchange.com/a/1590/250119
• tabularx package credit to https://tex.stackexchange.com/a/108544/250119
• bidiftnxtra package credit to https://tex.stackexchange.com/a/109564/250119
• nicematrix package credit to https://tex.stackexchange.com/a/645484/250119 or https://tex.stackexchange.com/a/612195/250119
• tabularray package credit to https://tex.stackexchange.com/a/614393/250119
• no package, use raw \footnotemark and \footnotetext and \addtocounter{footnote}{...} credit to https://tex.stackexchange.com/a/109470/250119 or https://tex.stackexchange.com/a/1607/250119

Features to be tested:

1. hyperref support
2. footnotetext are placed on the correct page where the footnotemark appear for floating table
3. automatic numbering when there are multiple footnotes
4. footnotes are placed below the table/at the bottom of the page
5. support for tabular environment itself without table environment around it
6. support for floating environment, tabular inside table

Result:

Package	1	2	3	4	5	6
footnotehyper	yes	no	yes	bottom of the page	yes	yes
footnote	one link per table	no	yes	bottom of the page	yes	yes
tablefootnote	yes	no	yes	bottom of the page	no	yes
longtable	only go to last page	no	yes	bottom of the page	yes	yes
ftnxtra	no	no	yes	bottom of the page	yes	no
threeparttable	no	yes	yes	below the table	yes	yes
tabularx	no	no	yes	bottom of the page	yes	no
bidiftnxtra	no	no	yes	bottom of the page	yes	no
nicematrix	yes	no	yes	both supported	yes	no
tabularray	yes	yes	no	below the table	yes	yes
raw footnotemark/footnotetext	one link per table	no	yes	bottom of the page	yes	no
