Your script has 2 problems (actually 3 but 2 of them are the same).  In
for(x=0; x<=ary.length; x++){
    for (i=0; i<=ary.length; x++){
        tbl += "<tr><td>"+ary[x][i]+"</td><td>"+ary[x][1]+"</td></tr>";
        //alert(tbl);
    }
}

Open in new window

  1. You should change "<=" to "<" in both for loops, otherwise it will iterate through the non-existing ary[ary.length] which throws an exception.
  2. In the inner loop, you have a typo: it should be "i++" instead of "x++"
