I tried following approach to solve this issue , it works with FF but not with Chrome.
::ng-deep div.ag-cell-value {
-webkit-touch-callout: default;
-webkit-user-select: text;
-khtml-user-select: text;
-moz-user-select: text;
-ms-user-select: text;
user-select: text;
cursor:auto;
}
Text selecting randomly even from other cells in chrome check below,
Please check the issue by adding this css to below standard template , https://stackblitz.com/edit/ag-grid-angular-hello-world
Instead of using CSS, have you tried using the enableCellTextSelection
option?
<ag-grid-angular
style="width: 500px; height: 200px;"
class="ag-theme-alpine"
enableCellTextSelection="true"
[rowData]="rowData"
[columnDefs]="columnDefs">
</ag-grid-angular>
