我已经解决了自己的问题.

I have solved question from myself.

我已经完成以下操作:

 { name: 'Edit', index: 'Edit', width: 80, align: 'center', editable: false, formatter: editFmatter, unformat: unformatEdit }

和

function editFmatter(el, cellval, opts) {
        var editHTML = "<img src='Images/row_edit.gif' alt='Edit' title='Edit' onclick='openEditDialog(" + opts.rowId + ");'>";
        var deleteHTML = "<img src='Images/row_delete.gif' alt='Delete' title='Delete' onclick='openDeleteDialog(" + opts.rowId + ");'>"; ;
        var finalHTML = editHTML + " " + deleteHTML;
        $(el).html(finalHTML);
    }
    function unformatEdit(cellvalue, options) {
        //return $(el).html().attr("originalValue");
    }
