用Function(props):VNode方法；亲测可用
<a-table
:expandIcon="props => customExpandIcon(props)"

<script> export default { methods:{ customExpandIcon:function(props) { if (props.expandable) { //根节点 if (props.expanded) { //是否已经展开 //已经展开 return ( { props.onExpand(props.record, e); }} icon="caret-down" > ); } else { //未展开 return ( { props.onExpand(props.record, e); }} icon="caret-right" > ); } } else { //叶子节点，不显示按钮 return ; //占位 } } } } //希望帮到你，哈哈

1.6.1 版本中 expandIcon方法删除了，我并没有找到，之前的老版本是可以用的，可以试试1.3.17版本，请问在新版本中有什么好的方法可以实现table 自定义展开图标嘛？
