Set the width of a column using table td:nth-of-type()

Let's assume that you are working with the following table:

html
<div className = 'Table'>
    <table>
        <thead>
            <tr>
                <th>Today</th>
                <th>Tomorrow</th>
            </tr>
        </thead>
        <tbody>
            <tr>
                <td>Code</td>
                <td>Read</td>
            </tr>
        </tbody>
    </table>
</div>

Let's assume that you want to set the width of the first column to 200px:

CSS
.Table td:nth-of-type(1),
.Table th:nth-of-type(1){
    width: 200px;
}

Important: you should modify both td and th width. Otherwise, the width will remain constant.
