How can tables be marked in HTML so they can be counted or selected for editing?

Tables in HTML can be marked using the "id" attribute. This attribute assigns a unique identifier to the table, allowing it to be easily selected for editing or manipulation using JavaScript or CSS. To mark a table, simply add an "id" attribute to the <table> tag with a unique value. ```html <table id="myTable"> <tr> <td>Row 1, Cell 1</td> <td>Row 1, Cell 2</td> </tr> <tr> <td>Row 2, Cell 1</td> <td>Row 2, Cell 2</td> </tr> </table> ```
