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 array, amsmath, pgfcore, and the module shapes of PGF.
