# CTAN update: nicematrix

Date: August 20, 2020 8:43:11 PM CEST

François Pantigny submitted an update to the
nicematrix
package.
Version number: 5.2 2020-08-19
License type: lppl1.3
Summary description: Improve the typesetting of mathematical matrices with PGF
Announcement text:

The vertical rules (specified by | or || in the preamble) respect the blocks (created by \Block). New key 'respect-blocks' for the command \rowcolors (with a s) in the 'code-before'. The variable '\g_nicematrix_code_before_tl' is now public. The key 'baseline' can take in a value of the form 'line-i' to align the tabular with a '\hline' drawn in the row 'i'. The key 'hvlines-except-corners' may take in as value a list of corners (eg: NW, SE).

## nicematrix – Improve the typesetting of mathematical matrices with PGF

This package is based on the package array. It creates PGF/TikZ nodes under the cells of the array and uses these nodes to provide functionalities to construct tabulars, arrays and matrices.

Among the features :

- continuous dotted lines for the mathematical matrices;
- exterior rows and columns (so-called border matrices);
- control of the width of the columns;
- tools to color rows and columns with a good PDF result;
- blocks of cells;
- tabular notes;
- etc.

The package requires and loads
l3keys2e,
array,
amsmath,
pgfcore,
and the module `shapes` of
PGF.
