MUI-DATATABLES onDownload函数给出未定义

Question

调用回调函数获取值并在中呈现

onDownload: (buildHead, buildBody, columns, data) => {
if (this.state.isexceldownload) {
this.callbackMethod((d) => {
console.log(d);
let val = `${buildHead(columns)}${buildBody(d)}`.trim();
console.log(val)
return val
});
}
}

单击后，它将下载第一个单元格上有未定义的CSV文件。

val中的数据集是：

"Col-1","Col-2","Col-3","Col-4","Col-5","Col-6","Col-7"
"007","Car","","US","","Matte Black","Available"
"009","Bike","","UK","","Blue","Available"

我想知道，我哪里错了。提前感谢

Answer 1

当文件下载为CSV而不是时，操作任何想要更改的数据后

let val = `${buildHead(columns)}${buildBody(d)}`.trim();
console.log(val)
return val

尝试返回此

return "uFEFF" + buildHead(columns) + buildBody(data);
