Used in conjunction with {{begin columns}} to create columns on a page that aren't formatted to fill the width of the page and can have the spacings between them specified. The latter is achieved using the gap parameter:
Use edit
previous column's contents
{{next column|gap}}
next column's contents
gap may be anything that maintains the syntax of width="gap" within wikicode for a table, e.g. "50px" (50 pixels), "90%". If it is omitted, i.e.
previous column's contents
{{next column}}
next column's contents
...then a default gap of 20px is used.
For examples, see {{begin columns}}.
