Implement DatePicker in an editable cell using ag-grid

I’m using ag-Grid in my project. I need to get an editable cell with a datepicker. For reference, I have provided code that I implemented for drop-down. Can anyone help me to convert this element to DatePicker?

var columndefs = [      
     { field: 'expires', headerName: 'Expiry Date', width: 150, editable: true, cellEditor: dropdownCellEditor, cellEditorParams: celleditorparams}
];
