我有一个JSON，我应该在此基础上准备HTML。请在下面找到我的JSON
{
"apiName": "myapi-v10",
"eventKey": "monitor_records",
"emailSubject": "local: PLAYER Records",
"customFields": {

我需要遍历customFields-> emailData表并访问其中的每个值。我尝试了多种方法，但似乎都没有解决，并抛出以下异常。
For "." left-hand operand: Expected a hash, but this has evaluated to a method+sequence
以下使用的FTL代码段
<div style="font-family: Arial, Helvetica, sas-serif; font-size: 10pt;">
<#assign tableValues = customFields.emailData?values>
<#assign tableKeys = customFields.emailData?keys/>
<#list tableKeys as tableKey>
<#assign seq_index = tableKeys?seq_index_of(tableKey) />
<#assign tableValue = tableValues[seq_index]/>
<table class="demo">
<caption>${tableValue.title}</caption>
<thead>
<tr>
<#list tableValue.headers as header>
<th>${header}</th>
</#list>
</tr>
</thead>
<tbody>
<#assign rows = table.data>
<#list rows as row>
<tr>
<#list tableValue.headers as header>
<td>${row[header]}</td>
</#list>
</tr>
</#list>
</tbody>
</table>
<p> </p>
</#list>
</div>
注意：我使用的是2.3.23 freemarker版本，由于需要大量批准，因此无法升级或降级为其他版本。
也欢迎提出任何有关修改JSON的建议，这些建议将使ftl代码更容易。
尝试解析标题本身时失败。
