How can CSS Flexbox be used to enhance the responsiveness of tables, especially when dealing with varying amounts of content within cells?

Flexbox is a CSS layout module that allows items within a container to be dynamically arranged depending upon certain conditions. When applied to tables, Flexbox can enable cells to wrap, expand, or stack based on the viewport size and the content within them. For example, in narrower viewports, table rows can be displayed as stacked blocks (or cards) with cells becoming block-level elements instead of being displayed in a row. This can offer a more optimized view of table content on mobile devices or smaller screens, ensuring that content remains accessible and legible regardless of the amount of content within each cell or the device used.
