Answer 1

Javascript代码：

var multiArray; 
window.onload = function() { 
    // load the table into the multidimensional array. 
    multiArray = []; 
    var trs = document.getElementsByTagName('TR'); 
    for(var i = 0; i < trs.length; i++) { 
     var arr = []; 
     var tds = trs[i].childNodes; 
     for(var j = 0; j < tds.length; j++) { 
      var td = tds[j]; 
      if (td.tagName === 'TD') { 
       arr.push(td.innerHTML); 
      } 
     } 
     multiArray.push(arr); 
    } 
    // perform some calculations between the columns of the array 
    var resCalc = []; 
    for(i = 0; i < multiArray.length; i++) { 
     resCalc[i] = 0; 
     for(j = 0; j < multiArray[i].length; j++) { 
      resCalc[i] += multiArray[i][j]; 
     } 
    } 
    // insert the results into a column of the same array 
    var columnToModify = 0; // the index of the column you want to change 
    for(i = 0; i < multiArray.length; i++) { 
     multiArray[i][columnToModify] = resCalc[i]; 
    } 
};
