formatSex: function (row, column) {

或者多個的話

formatMsgType: function (row, column) {
                switch (row.msgType) {
                    case ("text"):
                        
 
return '文字';
                        break;
                    case ("image"):
                        return '圖片';
                        break;
                    case ("voice"):
                        return '語音';
                        break;
                    case ("video"):
                        
 
return '視訊';
                        break;
                    case ("shortvideo"):
                        return '小視訊';
                        break;
                    case ("location"):
                        return '地理位置';
                        break;
                    case ("link"):
                        
 
return '連結訊息';
                        break;
                }
            },
