```
    <table border-bottom = 2>
        <th, td >
        {
            padding: 15px;
            text-align: left;
        }

        <tr:hover {background-color:#f5f5f5;}></tr>
    </table>

```

Writing in the above fashion throws errors. What's the syntax for Angular?

**Please show an example of combining `th`, `td` kind of properties with `ngClass`/`ngStyle` or anything else that is applicable.**
