Please override some css classes. For example, to get a higher height of tree node, simply add 'padding' to '.tree-node'.

Code:

<style>
  .tree-node{padding:5px 0}
</style>

If I want to use larger icon of the special row,how to code,please?

Bug:
"formatter" of tree options is invalid when lazy loading.
