# tabu

## tabu - Flexible LaTeX tabulars

tabu provides a single environment: tabu designed to make all kind of tabulars provided that they do not split accross pages.

tabu is based on array.sty and requires no other package. tabu does not modify array.sty nor the classes of tokens.

Starting from version 1.5, longtabu is provided: based on longtable, longtabu allows tabulars to stretch out on several pages.

tabu can be used in place of tabular, tabular and tabularx X columns in tabu can be specified with a width coefficient the alignement (l,r,c,j) the column type (p,m,b) or even \$.

tabu also works in math mode and its name remains tabu. tabu can contain any type of tabular, array, tabularx tabu can be put inside tabular, array, tabularx, tabular

begin{tabu} is like tabular if the preamble has no X column begin{tabu} to <dimen> specifies the target width begin{tabu} spread <dimen> enlarge the natural width

tabu with X columns has a default target if not specified (usefull for nested tabus + compatibility with linegoal)

tabu provides facilities to change the font and the alignment in one row (rowfont), save and restore the preamble and the tabular parameters (savetabu, usetabu, preamble).

tabu provides other facilities to align numbers in X columns draw lines with color, dashed or even leaders. Those facilities are provided for convenience: they work as long as the tabu preamble does not contain "too special tokens".

tabu has been tested successfully with many packages related to tabulars, cells, alignment...

## Emergency updates to the LaTeX tabu package

The original author of tabu appears out of contact, and tabu had not been updated for several years, finally becoming unusable in 2019 as updates to other packages mean some of its patched code did not work as intended.

The package is not being actively maintained however any major required fixes may be reported to the https://github.com/tabu-fixed/tabu repository and volunteers there (currently members of the 3 Team) will attempt to update the package with any fixes required.
