Bug: Table alignments not working on individual cells

[daniel-sc]

Describe the bug
The classes for alignment of table cells/rows/cols (sbb-table-align-center etc.) do not work on individual cells any more. This was working before and is documented: "You can use it in a single tr, th, td tag the alignment classes: sbb-table-align-center | sbb-table-align-left | sbb-table-align-right. In this example it has been used sbb-table-align-right to fix the text alignment of the last column to right." (see https://angular.app.sbb.ch/latest/content/table)

To Reproduce
See "Example" on https://angular.app.sbb.ch/latest/content/table - there the last column should always be aligned right, but instead follows the overall alignment for the whole table.

Expected behavior
The classes (sbb-table-align-center etc.) should work on individual cells (th, td) to be able to overwrite the alignment for specific columns.
