antd中table展开行默认展示,且不需要前边的加号操

 <Table
 expandedRowKeys={this.store.chargeTableData.map(item => item.key)} //展开的行
 expandIconAsCell={false}
 expandIconColumnIndex={-1}
 bordered     //展示边框
 defaultExpandAllRows={true}  //初始时展开所有行
 pagination={{ pageSize: 5 }}  //分页器
 expandedRowRender={this.expandedRowRender} //额外展开的行
 columns={columns}    //数据
 dataSource={this.store.chargeTableData} //数据数组
 />

 <Table 
  columns={this.columns}
  dataSource={tableData} 
  bordered 
  pagination={false}
  size='small'
  expandIconAsCell={false} 
  expandIconColumnIndex={-1}
  expandedRowRender={record=>this.expandedRowTable(record)}
  expandedRowKeys={this.state.expandArray}
  />

 const filtered = this.state.expandArray
 const text = this.state.expandBtnText 
 if(this.state.expandArray.includes(row.key)){
 filtered.splice(filtered.findIndex(element => element === row.key),1 );
 this.expandTdNum(parseInt(row.key,10),'reduce')

 this.setState({
