html - Table width border cellspacing cellpadding all 0 in HTML5 error validation -


i need use tables data changing html5 , new css. problem html5 validators giving me validation problems tables

here table

<table width="600" border="0" cellspacing="0" cellpadding="0">   <tr>     <td width="200"  align="left" valign="top"> td 1 must 200px width </td>     <td width="200"  align="left" valign="top"> td 2 must 200px width </td>     <td width="200"  align="left" valign="top"> td 3 must 200px width </td>   </tr> </table>

i tried css cannot make work. need have table 600px width, 1 tr , 3 td, each td must 200px (600px / 3 = 200 each )

tested adding style="align:left; valign:top;" not work. neither cellspacing or cellpadding. need no cellspacing no cellpadding no border don´t know how achieve ...

any ideas?

looked info online see new way of css add collapse or cannot understand how without spacing or padding

you avoid attributes with

table {   border-collapse: collapse;   width: 600px; }  table td {   vertical-align: top;   text-align: left }

and write simpler markup

<table>   <tr>     <td>td 1 must 200px width </td>     <td>td 2 must 200px width </td>     <td>td 3 must 200px width </td>   </tr> </table>

example: http://codepen.io/anon/pen/lvvemw (border inserted clarity purpose)

as can see every cell automatically 200px wide enter image description here
