Table color problems. Beginner

Table color problems. Newbie: this is the code I just typed. I originally wanted a line of yellow and a line of colorless, but somehow it turned completely yellow. let's take a look.

 
 
  ';} Else {echo'';}}For ($ j = 1; $ j <=$ I; $ j ++) {$ c = $ I * $ j; echo"
  
  
 
   
 
    
". $ J." * ". $ I." = ". ($ I * $ j ).""."
 
    
";} Echo"
";}?>

       ';}else{echo '';}for($j=1; $j<=$i; $j++){$c = $i * $j;echo "
       
       
 
        
 
         
".$j."*".$i."=".($i*$j)." "."
 
         
" ; }echo "
";}?>
 
        
 
       
      
      
 
 
 
      
      
       ';}else{echo '';}for($j=1; $j<=$i; $j++){$c = $i * $j;echo "

This is the current code. I don't understand why there is a large piece of space in the browser?
