如何在office js中创建表关系？

<script src="https://appsforoffice.microsoft.com/lib/1/hosted/office.js" type="text/javascript"></script>

var table1 = context.document.tables.getItemAt(0);
var table1Header = table1.getHeaderRowRange().load("values");
context.sync().then(function() {
    var binding = table1.bindToHeaderRowOrNullObject();
    context.sync().then(function() {
        // 创建表关系
    });
});

var table2 = context.document.tables.getItemAt(1);
var table2Header = table2.getHeaderRowRange().load("values");
context.sync().then(function() {
    var binding = table2.bindToHeaderRowOrNullObject();
    context.sync().then(function() {
        // 创建表关系
    });
});

context.workbook.bindings.addFromNamedItemAsync(binding1, binding2, "TableRelationship", "TableRelationship");
context.sync().then(function() {
    // 表关系创建成功
});
