Yes, you can easily use the index to get at an item like ${fields[i]}. You might want to loop over the indexes using something like:
是的，您可以轻松地使用索引来获取像${fields[i]}. 您可能希望使用以下内容循环索引：
<#list 0..fields?size-1 as i>
${fields[i]}
</#list>
Alternatively, you can just list over a sequence without the index like:
或者，您可以只列出没有索引的序列，例如：
<#list fields as field>
${field}
</#list>

you can use inbuilt index property of FMT: eg:
您可以使用 FMT 的内置索引属性：例如：
<#list ['a', 'b', 'c'] as i> ${i?index}: ${i}
<#list ['a', 'b', 'c'] as i> ${i?index}: ${i}
