HTML table can't remove borders

You should also set border:none; and outline:none; for the td element (not only for the table itself) and border-collapse: collapse;

Since you're having the class "nothing", try:

.nothing
{
   border-collapse:collapse;
} 
.nothing td
{
   border:none;
   outline:none;
}

Try border-collapse: collapse

Just try this:

style="border-collapse: collapse;"
