创建表记录-Google电子表格API

我试图通过《开发者指南:Java》学习如何使用Google电子表格API。我的应用程序可以对电子表格服务进行身份验证,检索基于工作表的提要并创建表。下一步是创建一个表记录我正在尝试做的事情。我的问题是在运行应用程序时出现以下错误:

Service failure
com.google.gdata.util.InvalidEntryException: Bad Request
[Line 1, Column 429, element entry] Required extension element  http://schemas.google.com/spreadsheets/2006:header not found.

这是创建表的代码部分:

//Creating a table record
String nameValuePairs = "Column A=Rosa";
RecordEntry entryToChange = new RecordEntry();
// Split first by the commas between the different fields.
for (String nameValuePair : nameValuePairs.split(",")) {
    // Then split by the equal sign.
    String[] parts = nameValuePair.split("=", 2);
    String name = parts[0]; // such as "name"
    String value = parts[1]; // such as "Fred"

    entryToChange.addField(new Field(null, name, value));         
}
try {
    myService.insert(tableFeedUrl, entryToChange);
} catch (IOException e) {
    System.err.println("I/0 problem");
    e.printStackTrace();
} catch (ServiceException e) {
    System.err.println("Service failure");
    e.printStackTrace();
}

tableFeedUrl:

tableFeedUrl = factory.getTableFeedUrl(entry.getKey());

条目:

entry = spreadsheets.get(0);

显然问题来自:

myService.insert(tableFeedUrl, entryToChange);

谢谢你的帮助。
