By applying this property to the container element of the table, the columns will be displayed as rows and the rows will be displayed as columns. Additionally, the `flex-direction` property can be used to specify whether the items should be displayed in a row or column layout. This allows for easy transformation of the table structure without changing the HTML markup. **
