### Why is this important?
Complex data tables require valid programmatical association between data cells and header cell using the `scope` attribute.
This data-to-header relationship is conveyed through assistive technology and helps the user understand the data presented in the table.
<!-- This is where the code snippet is injected -->
<div id="locSnippet"></div>
### What to do
* If this table only has headers in the first row and/or column, the `scope` attribute is not needed
* **Or**, to indicate a row header, use `<th scope="row">`
* **Or**, to indicate a header for a group of rows, use `<th scope="rowgroup">`
* **Or**, to indicate a column header, use `<th scope="column">`
* **Or**, to indicate a header for a group of columns, use `<th scope="colgroup">`
