title: Style CSS table td
body: <p>My site allows users to generate tables with PHP.  The number of rows and cells is variable but the number of columns is always fixed.  The table usually generates two digit numbers. When the table generates three digit numbers the entire table expands to accommodate this and the size of the table increases, ruining my layout.  Is there a way to use CSS and style this table's tds so that the table doesn't change size when 3 digit numbers are generated.  (3 digits are the longest).  I tried adding padding to the table, but its not working.</p>
  
  <p>Also, should I use an id in table or class?</p>
