SpreadJs v14.2.3 拖拽如何不覆盖tag

目前拖拽会把所有属性都覆盖过来，如何不改tag，只要值公式和样式？autoFillType里面没有合适的类型

请参考如下代码，缓存拖拽区域tag：

1. var dragTagCatch;
   
2. spread.bind(GC.Spread.Sheets.Events.DragFillBlock, function (s, e) {
   
3.   var sheet = e.sheet,
   
4.     fillRange = e.fillRange;
   
5.   dragTagCatch = [];
   
6.   for (var i = 0; i < fillRange.rowCount; i++) {
   
7.     dragTagCatch[i] = [];
   
8.     for (var j = 0; j < fillRange.colCount; j++) {
   
9.       dragTagCatch[i][j] = sheet.getTag(fillRange.row + i, fillRange.col + j);
   
10.     }
    
11.   }
    
12.   console.log(dragTagCatch);
    
13. });
    
14. spread.bind(GC.Spread.Sheets.Events.DragFillBlockCompleted, function (s, e) {
    
15.   var sheet = e.sheet,
    
16.     fillRange = e.fillRange;
    
17.   console.log(sheet.toJSON());
    
18.   for (var i = 0; i < fillRange.rowCount; i++) {
    
19.     for (var j = 0; j < fillRange.colCount; j++) {
    
20.       sheet.setTag(fillRange.row + i, fillRange.col + j, dragTagCatch[i][j]);
    
21.     }
    
22.   }
    
23.   console.log(sheet.toJSON());
    
24. });
