.net中創建table添加列

DataTable dt = new DataTable();
                dt.Columns.Add("name", Type.GetType("System.String"));
                dt.Columns.Add("date", Type.GetType("System.String"));
                dt.Columns.Add("type", Type.GetType("System.String"));
 
                for (int i = 0; i < PiciList.Count; i++)
                {
                    if (PiciList[i].Length == 3)
                    {
                        DataRow dr = dt.NewRow();
                        dr["name"] = PiciList[i][0];
                        dr["date"] = PiciList[i][1];
                        dr["type"] = PiciList[i][2];
                        dt.Rows.Add(dr);
                    }
                }
                if (dt != null && dt.Rows.Count > 0)
                {
                    for (int i = 0; i < dt.Rows.Count; i++)
                    {
                        sb.Append("");
                        sb.Append(" " + dt.Rows[i]["name"] + "");
                        sb.Append(" " + dt.Rows[i]["date"] + "");
                        sb.Append(" " + dt.Rows[i]["type"] + "");
 
                        sb.Append(" " + GetBindStatus(dt.Rows[i]["name"].ToString(), dt.Rows[i]["date"].ToString(), dt.Rows[i]["type"].ToString()) + "");
                    }
 
                    strHtml += sb.ToString();
                }
