Answer 1

You can quickly benefit from inherit behaviour of CSS ( Cascading Style Sheets ), by inlining them through the 'style' attribute oh html tags:

<table>
<tr style="background:red;"> <!-- behaviour of <tr> is to apply style to childs <td> -->
<td>red</td>
<td>red</td>
<td>red</td>
</tr>
<tr style="background:red;"> <!-- 'background' is shorthand property can be used for color -->
<!-- ... -->
</tr>
</table>

Keep just in mind that's inlined css are to be avoided, even you can make some exceptions, like for testing/debuging purposes, else externalized css ( in <style> tag or referenced in <link> tag as external file ) are to be prefered ;)

Answer 2

you must learn and use css to do this.
ex: td{
background-color:red;
}
