AWS 文档中描述的 AWS 服务或功能可能因区域而异。要查看适用于中国区域的差异，请参阅中国的 AWS 服务入门。

步骤 1：创建表

在此步骤中，您将创建一个名为 Movies 的表。表的主键由以下属性组成：

year – 分区键。AttributeType 为 N，表示数字。
title – 排序键。AttributeType 为 S，表示字符串。

将以下程序复制并粘贴到名为 MoviesCreateTable.html 的文件中：

    dynamodb.createTable(params, function(err, data) {
        if (err) {
            document.getElementById('textarea').innerHTML = "Unable to create table: " + "\n" + JSON.stringify(err, undefined, 2);
        } else {
            document.getElementById('textarea').innerHTML = "Created table: " + "\n" + JSON.stringify(data, undefined, 2);

<body>

<textarea readonly id= "textarea" style="width:400px; height:800px"></textarea>

</body>
</html>

注意

设置终端节点以指示您正在计算机上的 DynamoDB 中创建表。
在 createMovies 函数中，您需要指定表名称、主键属性及其数据类型。
ProvisionedThroughput 参数是必填项；但 DynamoDB 的可下载版本将忽略此参数。（预置的吞吐量不在此教程的讨论范围内。）

在您的浏览器中打开 MoviesCreateTable.html 文件。
选择 Create Table (创建表)。
