Using CSS to Center Text within Column Groups

Colgroups are valuable tools for applying uniform formatting to tables. While they effectively control background colors, many struggle to achieve text alignment with them. Let's explore the reasons behind this limitation and find practical solutions for aligning text within column groups.
