调用实例：

Console.WriteLine("Hello, World!");List<string[]> tabLog = new List<string[]>();
tabLog.Add(new string[] { "编号", "姓名", "性别", "年龄","备注" });
tabLog.Add(new string[] { "1", "张三", "男", "12","这个地方的数据可能很长" });
tabLog.Add(new string[] { "2", "李四", "不清不楚的", "15", "这个地方的数据可能很长很长" });
tabLog.Add(new string[] { "3", "王五", "女", "10" ,"短了"});var strLog = TableDataToStr(tabLog.ToArray());Console.WriteLine(strLog);
