如何更改智能表格任意一列的日期格式

Question

这是我的自定义管道，我用它来更改时刻的日期。例如：1个月前

import { Pipe, PipeTransform } from '@angular/core';
import * as moment from 'moment';
@Pipe({ name: 'createdDate' })
export class MomentPipe implements PipeTransform {
transform(createdDate:Date) {
const m=moment("createdDate").fromNow()
return m;
}
}

用于显示表标题列的此对象。

settings = {`enter code here`
createdDate: {
title: 'Date Created',
valuePrepareFunction: (createdDate) => {
if (createdDate) {
return new MomentPipe().transform(createdDate ,  'M/d/yyyy');
}
return null;
}, } } };

更改管道代码：

import { Pipe, PipeTransform } from '@angular/core';
import * as moment from 'moment';
@Pipe({ name: 'createdDate' })
export class MomentPipe implements PipeTransform {
transform(createdDate:Date) {
const m=moment(createdDate).fromNow()
return m;
}
}
