Html 角料台：can'；t绑定到'；matRowDefColumn'；

我试图使用一个有角度的材料表。我导入了模块，但出现了模板解析错误。 HTML:

数据源：我使用

returnDeadProjectList（）

我得到的错误是：

compiler.js:466 Uncaught Error: Template parse errors:
Can't bind to 'matRowDefColumn' since it isn't a known property of 'mat-row'.
1. If 'mat-row' is an Angular component and it has 'matRowDefColumn' input, then verify that it is part of this module.
2. If 'mat-row' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.
3. To allow any property add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component.

如果我在

schemas:[]中写入
CUSTOM\u ELEMENTS\u SCHEMA
，

我会得到一个不同的错误：

compiler.js:466 Uncaught Error: Template parse errors:
Property binding matRowDefColumn not used by any directive on an embedded template. Make sure that the property name is spelled correctly and all directives are listed in the "@NgModule.declarations". ("`  `<mat-header-row *matHeaderRowDef="displayedColumns"></mat-header-row>
      [ERROR ->]<mat-row *matRowDef="let row; column: displayedColumns;"></mat-row>

compiler.js:466未捕获错误：模板分析错误：
嵌入模板上的任何指令均未使用属性绑定matRowDefColumn。确保属性名称拼写正确，并且所有指令都列在“@NgModule.declarations”中。("`  `

有人知道我缺少什么吗？我应该有我需要的所有导入，但不知怎么的，它找不到元素。此外，我甚至不使用

matHeaderRowDef

将此代码添加到你的.component.ts和app.module.shared.ts中

它对我有用

 import {
    MatPaginator, MatSort, MatTable, MatTableModule, MatTabHeader,
    MatHeaderRow, MatHeaderCell, MatHeaderCellDef, MatHeaderRowDef,
    MatSortHeader, MatRow, MatRowDef,  MatCell, MatCellDef,
    _MatCell, _MatCellDef, _MatHeaderCellDef, _MatHeaderRowDef
} from '@angular/material';
@NgModule({
    imports: [MatPaginator, MatSort, TableDataSource,
        CdkTableModule, MatTable, MatTableModule],
    schemas: [CUSTOM_ELEMENTS_SCHEMA, NO_ERRORS_SCHEMA],
    declarations: [
        MatTabHeader,
           MatHeaderRow,
        MatHeaderCell,
        MatHeaderCellDef,
        MatHeaderRowDef,
        MatSortHeader,
            MatRow,
        MatRowDef,
        MatCell,
        MatCellDef,
        _MatCell,
        _MatCellDef,
        _MatHeaderCellDef,
        _MatHeaderRowDef
    ]
})

代码片段

属性名称有问题。MatRowDef有属性列而不是列。 换成

之后它应该可以工作。

您能创建plunkr模板吗？
