For rendering nested data, the prop `row-key` is required。Also, child row data can be loaded asynchronously. Set `lazy` property of Table to true and the function `load`. Specify `hasChildren` attribute in row to determine which row contains children. Both `children` and `hasChildren` can be configured via `tree-props`.
