React Antd 的ProTable 如何默认展开树结构

1、defaultExpandAllRows:true   defaultExpandAllRows设为true就可以了

<ProTable
                            rowKey="key"
                            columns={rightBomColumnArr}
                            dataSource={rightBomTableTreeData}
                            search={false}
                            pagination={false}
                            recordCreatorProps={false}
                            toolbar={false}
                            options={false}
                            scroll={{ x: '100%', y: 400 }}
                            expandable={{
                                defaultExpandAllRows:true
                            }}>
                        </ProTable>
