问题描述与截图：

When filtering a tree table (virtualized) with configuration tree-config.transform = true the filter is not applied to the children

• ✅ When i filtered without children filter is ok (2021-11-18)
• 🐛 When I filtered with childrens, filter does not apply to children (2021-11-20).

I think the error may be here since when filtering if treeOpts.transform == true, tableData should be transformed to an array XEUtils.toTreeArray (tableData)

期望的结果：

filter-method should receive every row (not a tree) to be able to filter every child
