What is a table header?

Can I have multiple table headers on a single table?
Absolutely, you can. In fact, most tables would be quite impractical without multiple headers. Each column in your table should typically have its own header, providing a brief description of the data it holds.
Does the order of table headers matter?
Yes, it does. The order of your table headers can greatly affect how easily the data on your table can be understood. You should arrange your table headers in a logical and intuitive order that makes sense for the data you're working with.
Could I use a table without a header?

Does the size of a table affect the way I should create table headers?
The size of your table doesn't necessarily dictate how you should create your table headers.

However, if your table is particularly large, you might want to consider using shorter headers to save space.
What should I do if my table header doesn’t fit the column width?
