Question

我正在使用Office JS API处理Word加载项，尝试在文档中的表绑定周围添加内容控件。

我遇到的问题是在选择围绕表的Binding后，使用goToByIdAsync()，内容控件仅围绕表的最后一行创建，而不是选择。返回ctx.document.getSelection()的值我可以看到所选范围只是选定表中的最后一行。我需要使用Binding对象来了解Table的选定单元格范围。有什么我做错了吗？

var bindingId  = '123';
var doc        = Office.context.document;

    // Create table in document.
    doc.setSelectedDataAsync(tableValue, { coercionType: Office.CoercionType.Table }, function (asyncResult) {

            // Add Binding to table
            doc.bindings.addFromSelectionAsync(Office.BindingType.Table, { id: bindingId }, function (asyncResult) {

                    // Select the table object                        
                    doc.goToByIdAsync(bindingId, Office.GoToType.Binding, { selectionMode: 'selected' }, function (asyncResult) {

                         // Create Content Control
                         createCC();
                    });

            });
    });


    function createCC(){
         Word.run(function (ctx) {
             var range = ctx.document.getSelection();
             var html  = range.getHtml();

                 return ctx.sync().then(function () {
                     console.log('Selected Range', html.value); // Only displays last row in the table.

                     var myContentControl = range.insertContentControl();
                         myContentControl.tag = bindingId;
                         myContentControl.title = 'My Content Control';

                         return ctx.sync().then(function () {
                                    //Content control for table created
                                });
                           }).catch(function (err) {
                               errorHandler(err);
                           });
                    });
    }

这是一个很好的问题！谢谢你的提问。我建议你改变一下如何实现你想要的方案的方法。首先，goToById不应该用于获取任何对象的范围，这仅用于导航目的。如果你可以插入一个表，用一个命名的内容控件包装它（为它指定一个标题），创建一个绑定（使用addFromNamedItem而不使用addFromSelection，因为你没有一个可靠的选择:)，这将更具确定性。），然后只需订阅bindingSelectionChanged事件，并执行您需要对表或选定单元格执行的任何操作。

以下代码显示了这一点。希望它会让你朝着正确的方向前进。我在上面描述的每个步骤中添加了一堆注释。

感谢和快乐的编码！
