Whether or not it is a disadvantage depends on what you are trying to do with the table.
You can relate the data present in multiple tables by using the concept of Foreign Keys. for example if we have an employee database that contains various details of an employee scattered in multiple tables, one column in each table can be used to logically group the data in all these tables. For example, the employee number column in each of these tables can be used to relate the data present in these tables.
In SQL, you join tables using the JOIN clause, which allows you to combine rows from two or more tables based on a related column. The most common types of joins are INNER JOIN, which returns rows with matching values in both tables; LEFT JOIN, which returns all rows from the left table and matched rows from the right table; and RIGHT JOIN, which does the opposite. You specify the joining condition using the ON keyword, typically comparing primary and foreign keys. For example: SELECT * FROM table1 INNER JOIN table2 ON table1.id = table2.foreign_id;.
