如何让按钮在 angular-ui- 网格单元格中居中?

How do I center a button in an angular-ui-grid cell?

我定义一列如下:

{
  name: 'button', 
  displayName: '', 
  cellClass: 'ui-grid-vcenter',
  enableColumnMenu: false,
  enableFiltering: false,
  enableSorting: false,
  cellTemplate: '<div><button ng-click="grid.appScope.rowButtonHandler(row.entity.id)">clicky</button></div>'
}

导致:

<div class="ui-grid-cell ng-scope ui-grid-coluiGrid-010 ui-grid-vcenter" ui-grid-cell="" ng-class="{ 'ui-grid-row-header-cell': col.isRowHeader }" ng-repeat="(colRenderIndex, col) in colContainer.renderedColumns track by col.colDef.name">
    <div class="ng-scope">
        <button ng-click="grid.appScope.rowButtonHandler(row.entity.id)"></button>
    </div>
</div>

我想将此按钮垂直和水平居中。在水平方向上有效,但在垂直方向上,我似乎无法正确设置 CSS。这是我的通用镜头:

.ui-grid-vcenter div {
  text-align: center;
  vertical-align: middle !important;
  background-color: yellow !important;
}

在这种AngularJS网格中,一个单元格中的内容如何居中?

使用相对位置:

.ui-grid-vcenter div {
  background-color: yellow !important;
  text-align:center;
  position: relative;
  top: 50%;
   -webkit-transform: translateY(-50%);
  -ms-transform: translateY(-50%);
  transform: translateY(-50%);
}

使用 css flex 会更容易 (https://css-tricks.com/snippets/css/a-guide-to-flexbox/):

假设那是你的 cellTemplate (myCellTemplateForEditAndDelBtns.html):

<div id="editBtns" class="flexParent">
<span  class="flexChildren">
    <button><i class="fa fa-pencil-square-o "></i></button>
    <button><i class="fa fa-times gridDelBtn"></i></button>
</span>
</div>

您在 columDefs 中将其添加到您的单元格中:

$scope.myGrid.columnDefs = [
    ...
    { name: 'edit',
        enableCellEdit: false,
        enableFiltering: false,
        enableSorting: false,
        cellTemplate: 'location-to/myCellTemplateForEditAndDelBtns.html',
        width: '5%'
    }
];

并且最终使用CSS Flex:

#editBtns {
    height: 100%;
}

.flexParent {
    display: flex;
    justify-content: center;
}

.flexChildren {
    align-self: center;
}
