TLDR

Use display: flex in a <div> inside your <td> to ensure min-height:

<td> <div style="min-height: 50px; display: flex; align-items: center;"> <!-- How high can you go? Content goes here :) --> </div> </td>

This design upholds min-height and vertically aligns your content, navigating around table layout restrictions.

Practical application of min-height in tables

The CSS min-height property doesn't apply to <table>, <tr>, or <td> elements per CSS 2.1. A practical and clever solution is wrapping content in a <div> with a min-height inside the <td>. It not only sets a minimum height but also paves a way for dynamic control over the table aesthetics.

Utilizing Flexbox for optimal control

The role of Flexbox is immense in setting up a flexible layout. It maintains a happy balance between a fixed minimum height and the capacity to expand in accordance with the content size.

Setting height as an alternative

When Flexbox seems a little bit much, you can go back to basics using the height property directly on table cells. It's straightforward and often adequate to ensure a consistent layout.

Preserving aesthetics with inner divs

Achieving the desired aesthetic can sometimes be a bit of a task. Wrapping the content in a <div> and setting a background color ensures consistency in visual experience, giving the illusion of min-height even while the actual cell size adjusts dynamically.

Flexbox and min-height: Use cases and quirks

Nested flex containers for centered content

For nested elements inside your table, having a flex container can be quite handy. It takes care of vertical and horizontal centering, providing a more professional and polished look to your content.

Balancing Collapsible content

When dealing with collapsible content and dynamic resizing, directly adding min-height or height to your cells can affect the overall layout. Planning your CSS with dynamic interactions in mind goes a long way in ensuring a smooth user experience.

Browser support: The good, the bad, and the ugly

For developers, browser support can often be the deciding factor when it comes to opting for certain CSS properties. For min-height within the flexbox context, do check for compatibility especially when supporting older browsers comes into the picture.

Scaling for larger tables: A cautionary tale

Performance issues can creep into larger tables that use nested elements extensively or complex CSS rules. Always ensure that your tables are lean and performant, and scale well in different environments.

Common pitfalls and best practices

Overflow: To wrap or not to wrap

Overflow can happen when content exceeds the cell's height. With flex containers, this can be managed elegantly with scroll bars or ellipsis.

The secret life of tables: Inherent minimum content size

Tables come with their own minimum content size based on their content. Bear in mind that using min-height on inner divs does not override this inherent quality.

Inline styles: A double-edged sword

While inline styles can be a quick-fix solution, for better maintenance and scalability, always opt for external CSS files when you are lining up for production.

Baking Accessibility into your Table

Jamming div elements inside table cells without considering accessibility can harm your table's semantic structure. So, don't throw semantics out of the window, even as you strive for the perfect layout.
