我打开一个电子表格，我可以在控制台中看到：
_clipBoardOptions: "All"
在 activeSheet 对象中。
但每当我尝试从 excel 粘贴格式时，它只会传递值。有什么想法我错了吗？
基本上默认是“全部”，但没有格式传递给SpreadJS 这是我的初始化
$("#ss").wijspread({sheetCount:1}); // create wijspread control
var spread = $("#ss").wijspread("spread"); // get instance of wijspread control
var sheet = spread.getActiveSheet();
同样当我尝试在初始化后手动添加方法时：
sheet.clipBoardOptions($.wijmo.wijspread.ClipboardPasteOptions[0])
我尝试寻找解决方案，但提供的信息不多，而且 api 有点糟糕！
在此先感谢您的任何帮助者！
SpreadJS 不支持从 Excel 粘贴格式。我们正在研究如何在未来的版本中实现对此的支持。
目前，SpreadJS 只能使用 ExcelIO Web 服务导入整个 Excel 工作簿。
要将单元格范围的内容复制到 SpreadJS，我现在最好的建议是使用 ExcelIO 将该工作簿导入隐藏的 SpreadJS 实例，然后使用 ClipboardPasteUndoAction 将范围从隐藏的 SpreadJS 复制并粘贴到可见的。
下面是一个代码示例，展示了如何使用 ExcelIO Web 服务导入 Excel 文件：

下面是一个代码示例，展示了如何使用 ClipboardPasteUndoAction：
$(document).ready(function () {
//There are two buttons in html page with the id "cutPasteBtn" and "copyPasteBtn".
var spread = new GcSpread.Sheets.Spread($("#ss").get(0),{sheetCount:3});
var sheet = spread.getActiveSheet();
sheet.setValue(0, 0, 1, GcSpread.Sheets.SheetArea.viewport);
sheet.setValue(1, 0, 2, GcSpread.Sheets.SheetArea.viewport);
sheet.setFormula(2, 0, "=A1+A2", GcSpread.Sheets.SheetArea.viewport);
sheet.setValue(0, 1, 3, GcSpread.Sheets.SheetArea.viewport);
sheet.setValue(1, 1, 4, GcSpread.Sheets.SheetArea.viewport);
sheet.setFormula(2, 1, "=B1+B2", GcSpread.Sheets.SheetArea.viewport);
var fromRange = new GcSpread.Sheets.Range(0, 0, 3, 2);
var toRanges = [new GcSpread.Sheets.Range(4, 0, 3, 2)];
$("#cutPasteBtn").click(function () {
//Cut Paste Action
var clipboardCutPasteAction = new GcSpread.Sheets.UndoRedo.ClipboardPasteUndoAction(sheet, sheet, sheet, { fromRange: fromRange, pastedRanges: toRanges, isCutting: true, clipboardText: "" }, GcSpread.Sheets.ClipboardPasteOptions.Values);
clipboardCutPasteAction.execute(sheet);
});
$("#copyPasteBtn").click(function () {
//Copy Paste Action
