Using CSS classes in table

A

I'm trying to use multiple classes in a table, although I am not combining them. I am using them at different parts of the table.

What I have is:

CSS
Code: 
.objs {
    text-align: center;
    font-size: 18px;
    font-weight: bold;
}

.tables {
    text-align: center;   
}

HTML
Code: 
<td class="tables">

<td class="course-title">

<td class="objs">

The only one I can get to work is the second one, class="course-title". The first one is nesting a table in a table. I want it centered, I have seen other forums and "how-to sites" say to do it the way I am, however the only way I can get the nested table centered is to use align="center". However HTML validators complain it is out of date, is it "ok" to use it. Is there a third option?

HTML: 
<table style="width:100%; border:hidden">
    <tr>
        <td style="text-align:right"></td>
    </tr>

    <tr>
        <td class="tables">
            <table style="width:62%; border:hidden">
                <tr>
                    <td class="course-title"></td>
                </tr>
                <tr>
                    <td class="objs-1"></td>
                  
                </tr>
                <tr>
                    <td class="objs-2">
                        <ul>
                            <li></li>
                            <li></li>
                            <li></li>
                            <li></li>
                        </ul>
                    </td>
                </tr>
            </table>
        </td>
    </tr>         
</table>

This is the HTML and CSS code for the nested tables including unordered list. I want to use the class "tables" to center the nest table.
