François Pantigny submitted an update to the
nicematrix
package.
Version number: 4.0 2020-05-08 License type: lppl1.3
Summary description: Improve the typesetting of mathematical matrices with PGF
Announcement text: ----------------------------------------------------------------------
New environment {NiceTabular}
This version of 'nicematrix' provides tools to color cells, rows and columns of tabulars, arrays and matrices (as does 'colortbl') but with a perfect result for PDF viewers (with some PDF viewers, some rules seem to vanish in the tabular constructed with 'colortbl').
Moreover, these functionnalities are compatible with 'booktabs'.
