每個行＆標題列的「編輯/刪除」按鈕是在md-table組件中的「動作」

Question

我在角度4世界中是相當新的，我試圖爲每行添加「編輯/刪除」按鈕&標題欄是Angular 4中Angular Material設計中md-table組件中的'Action'。我該怎麼做？爲每行定製標題列&按鈕。任何模板可用來做到這一點？下面是我的HTML代碼。

userinfo.html

<!-- ID Column --> 
<ng-container cdkColumnDef="username"> 
<md-header-cell *cdkHeaderCellDef> User Name </md-header-cell> 
<md-cell *cdkCellDef="let row"> {{row.username}} </md-cell> 
</ng-container> 

<!-- Email Column --> 
<ng-container cdkColumnDef="email"> 
<md-header-cell *cdkHeaderCellDef> Email </md-header-cell> 
<md-cell *cdkCellDef="let row"> {{row.email}} </md-cell> 
</ng-container> 

<!-- First Name Column --> 
<ng-container cdkColumnDef="userFirstName"> 
<md-header-cell *cdkHeaderCellDef> First Name </md-header-cell> 
<md-cell *cdkCellDef="let row"> {{row.userFirstName}} </md-cell> 
</ng-container> 

<!-- Last Name Column --> 
<ng-container cdkColumnDef="userLastName"> 
<md-header-cell *cdkHeaderCellDef> Last Name </md-header-cell> 
<md-cell *cdkCellDef="let row" [style.color]="row.color"> {{row.userLastName}} </md-cell> 
</ng-container> 

<!-- Phone Column --> 
<ng-container cdkColumnDef="userMobile"> 
<md-header-cell *cdkHeaderCellDef> Phone </md-header-cell> 
<md-cell *cdkCellDef="let row" > {{row.userMobile}} </md-cell> 
</ng-container> 

<!-- Role Column --> 
<ng-container cdkColumnDef="authority"> 
<md-header-cell > Role </md-header-cell> 
<md-cell *cdkCellDef="let row" > {{row.authority}} </md-cell> 
</ng-container> 

<!-- Action Column 
<md-header-cell > Action </md-header-cell> 
<md-cell > <button md-raised-button >Edit</button> </md-cell> --> 

<md-header-row *cdkHeaderRowDef="displayedColumns"></md-header-row> 
<md-row *cdkRowDef="let row; columns: displayedColumns;"></md-row> 

Answer 1

你是在正確的軌道上，你只需要一個actions項目添加到列表displayedColumns;

displayedColumns = ["username","email","userFirstName" ... ,"actions"]; 

和：

<ng-container cdkColumnDef="actions"> 
    <md-header-cell > Actions </md-header-cell> 
    <md-cell *cdkCellDef="let row" > 
     <button md-raised-button >Edit</button> 
    </md-cell> 
</ng-container> 

Answer 2

爲了執行編輯的邏輯/刪除的每一行，則可以使用angular4-material-table包，是基於angular4 + CDK表。
