树表格的懒加载，通过配置 <table-api-link prop="row-id"/> 和 <table-api-link prop="tree-config"/>={<table-api-link prop="lazy"/>, <table-api-link prop="loadMethod"/>} 加载方法来开启树形懒加载<br>
|
||
当启用懒加载后，必须通过 <table-api-link prop="hasChild"/> 属性来标识是否存在子节点，从而控制该节点是否允许被点击<br>
|
||
<span class="red">（注：懒加载启用后一次只允许异步加载一层根节点）</span>
