General struct

A worksheet ItemConf in HelloWorld.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!--
<@TABLEAU>
    <Item Sheet="ItemConf" />
</@TABLEAU>

<ItemConf>
    <Item ID="uint32" StartTime="datetime">
      <Expiry>duration</Expiry>
    </Item>
    <Item2 ID="{OtherItem}uint32" Name="string" />
</ItemConf>
-->

<ItemConf>
    <Item ID="1" StartTime="2024-10-01 10:10:10">
      <Expiry>1h</Expiry>
    </Item>
    <Item2 ID="1" Name="gold" />
</ItemConf>
