5.2 \twocolumn
Synopsis:
\twocolumn[text1col]
The \twocolumn
declaration starts a new page and produces
two-column output. If the optional text1col argument is present,
it is typeset in one-column mode before the two-column typesetting
starts.
These parameters control typesetting in two-column output:
\columnsep
- The distance between columns (35pt by default).
\columnseprule
- The width of the rule between columns; the default is 0pt, so there is no rule.
\columnwidth
- The width of the current column; this is equal to
\textwidth
in
single-column text.
These parameters control float behavior in two-column output:
\dbltopfraction
- Maximum fraction at the top of a two-column page that may be occupied
by floats. Default ‘.7’, can be usefully redefined to (say)
‘.9’ to avoid going to float pages so soon.
\dblfloatpagefraction
- The minimum fraction of a float page that must be occupied by floats,
for a two-column float page. Default ‘.5’.
\dblfloatsep
- Distance between floats at the top or bottom of a two-column float
page. Default ‘12pt plus2pt minus2pt’ for ‘10pt’ and
‘11pt’ documents, ‘14pt plus2pt minus4pt’ for ‘12pt’.
\dbltextfloatsep
- Distance between a multi-column float at the top or bottom of a page
and the main text. Default ‘20pt plus2pt minus4pt’.
