How do I view two tables side by side in SQL?
SQL joins allow you to combine two datasets side-by-side, but UNION allows you to stack one dataset on top of the other. Put differently, UNION allows you to write two separate SELECT statements, and to have the results of one statement display in the same table as the results from the other statement.
What makes a good table design?
A good data table has a clear header and description, so users know what they're viewing. Designers must also use legible typography and adequate spacing between columns and rows to make it easy for users to read and absorb content.
