One example of its use is when the text in the last
column of a |tabular| environment is set with ||; then
|| can be used to indicate the end of a row of the
|tabular|, whilst |
| will indicate the end of a line of text in a
paragraph within the column. This command can be used in the |array|
environment as well as |tabular|, and also the extended versions of
these environments offered by the array and longtable
packages in the tools collection.
