我已经将 Material UI 中的材料表用于 React。当数据静态传递时,它会逐行显示,但是当我从 Web 服务中获取数据时,已经添加了行更新而不是追加新行。请帮忙。
const [state, setState] = useState({
columns: [
{ title: 'S.No', field: 'Id', type: 'numeric', editable: 'never' },
{ title: 'Roll Number', field: 'Studentid' },
{ title: 'Name', field: 'Name', editable: 'never' },
{ title: 'Year', field: 'Year', editable: 'never' },
{ title: 'Department', field: 'DeptName', editable: 'never'},
],
data: eventRegistrationStudentsList,
});
<MaterialTable
style={{ maxWidth: "95%" }}
title="Student Details"
id="studentDetailsTable"
columns={state.columns}
data={eventRegistrationStudentsList}
editable={{
onRowAdd: newData =>
new Promise(resolve => {
const data = [...state.data];
data.push(newData);
setState({ ...state, data });
handleStudentIdChange(newData.Studentid);
resolve();
}),
onRowDelete: oldData =>
new Promise(resolve => {
setTimeout(() => {
resolve();
const data = [...state.data];
data.splice(data.indexOf(oldData), 1);
setState({ ...state, data });
}, 600);
}),
}}
options={{
search: false,
actionsColumnIndex: -1
}}
/>
eventRegistrationStudentsList 持有:
[ DeptName: "AERONAUTICAL ENGINEERING",
Id: 1,
Name: "Jon",
Studentid: "190AE101",
Year: "III" ]
