What replaces cellpadding, cellspacing, valign, and align in HTML5 tables?

In Visual Studio, I'm seeing these warnings:

• Validation (HTML 5): Attribute 'cellpadding' is not a valid attribute of element 'table'.
• Validation (HTML 5): Attribute 'cellspacing' is not a valid attribute of element 'table'.
• Validation (HTML 5): Attribute 'valign' is not a valid attribute of element 'td'.
• Validation (HTML 5): Attribute 'align' is not a valid attribute of element 'td'.

If they are not valid attributes in HTML5, what replaces them in CSS?

/* cellpadding */
th, td { padding: 5px; }

/* cellspacing */
table { border-collapse: separate; border-spacing: 5px; } /* cellspacing="5" */
table { border-collapse: collapse; border-spacing: 0; }   /* cellspacing="0" */

/* valign */
th, td { vertical-align: top; }

/* align (center) */
table { margin: 0 auto; }

This should solve your problem:

td {
    /* <http://www.w3.org/wiki/CSS/Properties/text-align>
     * left, right, center, justify, inherit
     */
    text-align: center;
    /* <http://www.w3.org/wiki/CSS/Properties/vertical-align>
     * baseline, sub, super, top, text-top, middle,
     * bottom, text-bottom, length, or a value in percentage
     */
    vertical-align: top;
}

On particular table

<table style="border-collapse: separate; border-spacing: 10px;" >
    <tr>
      <td>Hi</td>
      <td>Hello</td>
    <tr/>
    <tr>
      <td>Hola</td>
      <td>Oi!</td>
    <tr/>
</table>
