the first time you can"t get the data, the second time you get the data triggered by the first time, and then each time you get the data from the previous trigger
fetch data:
getExpandData = (param) => {
getModelVersion(param).then((result) => {
if (result) {
this.setState({
subData: result, //
});
}
});
};
expansion of nested subtables:
expandFunction = (expanded, record) => {
const { showListDom } = this.state;
if (record) { //
const param = {
modelId: record.id,
};
this.getExpandData(param); //
const subList = this.state.subData.map((v) => {
return {
...v,
todo: v.status,
};
});
const dom = (
<Table
columns={this.detailsColumns}
onChange={this.handleSubTableChange}
dataSource={subList}
rowKey={subList.id}
pagination={false}
/>);
const Id = record.id;
const item = {};
item[Id] = dom;
this.setState({
showListDom: {
...showListDom,
...item,
},
});
}
};
within the render method:
<Table
dataSource={this.state.SampleData}
rowKey={record => record.id || record.key}
columns={columns}
onChange={this.handleStandardTableChange}
pagination={this.state.pagination}
loading={this.state.loading}
expandedRowRender={(record) => { return this.state.showListDom[record.id] || null; }}
onExpand={(expanded, record) => this.expandFunction(expanded, record) || null}
/>
