width and/or height in tables are not standard anymore; as Ianzz says, they are depreciated. Instead the best way to do this is to have a block element inside your table cell that will hold the cell open to your desired size:

     
          
       
                
            
         
                
          
 
           Home 
          
            
         
        
                
Content
           
      
     

css

.content {
       width: 1000px;}.left_menu {
       background: none repeat scroll 0 0 #333333;    border-radius: 5px 5px 5px 5px;    font-family: Arial,Helvetica,sans-serif;    font-size: 12px;    font-weight: bold;    padding: 5px;    width: 200px;}.menu_item {
       background: none repeat scroll 0 0 #CCCCCC;    border-bottom: 1px solid #999999;    border-radius: 5px 5px 5px 5px;    border-top: 1px solid #FFFFCC;    cursor: pointer;    padding: 5px;}
