* Create a new list table package that extends the core WP_List_Table class. |
| 24 |
* WP_List_Table contains most of the framework for generating the table, but we |

* need to define and override some methods so that our data can be displayed |
| 26 |
* exactly the way we need it to be. |
| 27 |
* |
| 28 |
* To display this example on a page, you will first need to instantiate the class, |
| 29 |
* then call $yourInstance->prepare_items() to handle any data manipulation, then |
| 30 |
* finally call $yourInstance->display() to render the table to the page. |
| 31 |
* |
| 32 |
* Our theme for this list table is going to be movies. |
