Sharepoint 2010 啟用 Office Web Apps

最近研究Sharepoint 的共同編輯(Co-author)，發現Word / PowerPoint 都可以共同編輯，唯讀 Excel 不行，是沒裝好嗎?

發現不是，目前Excel 2010 並不支援共同編輯，必需採用Browser的方式才能共同編輯。
MS的說明如下：

The Excel 2010 client application does not support co-authoring workbooks in SharePoint Server 2010. However, the Excel client application does support non-real-time co-authoring workbooks stored locally or on network (UNC) paths by using the Shared Workbook feature. Co-authoring workbooks in SharePoint is supported by using the Microsoft Excel Web App, included with Office Web Apps. Office Web Apps is available to users through Windows Live and to business customers with Microsoft Office 2010 volume licensing and document management solutions based on Microsoft SharePoint 2010 Products. 

安裝Office Web Apps 除了裝好後，還需By Site 啟動Feature，步驟如下：

測試結果還真的滿陽春的。
第一個標簽頁：File，內含(Open in Excel / Where's the Save Button/ Save As / Download s shapshot/ Download a copy)
第二個標簽頁：Home，含有基本的Cut / Copy/ Paste / 字型/大小/斜體/ Table 的 Insert / delete 等..
第三個標簽頁：Insert，只有 Table / Hyperlink
沒了!

相對於MS Excel Web App SkyDrive 的功能上，至少SkyDrive 的Insert 標簽頁上，尚有函數及各式圖表可用(直條圖/折線圖/圓形圖/橫條圖/區域圖/散佈圖等)
