Osobiście utworzyłbym i dodałby kolumny do DataTable w ten sposób, ale od Ciebie zależy, czy spróbujesz to w ten lub inny sposób, o którym wiesz, że zadziała
DataTable table = new DataTable("ImageTable"); //Create a new DataTable instance.
DataColumn column0 = new DataColumn("id"); //Create the column.
column.DataType = System.Type.GetType("System.String"); //Type string
DataColumn column1 = new DataColumn("image"); //Create the column.
column.DataType = System.Type.GetType("System.Byte[]"); //Type byte[] to store image bytes.
column.AllowDBNull = true;
column.Caption = "My Image";
table.Columns.Add(column0); //Add the column to the table.
table.Columns.Add(column1); //Add the column to the table.
Then, add a new row to this table and set the value of the MyImage column.
DataRow row = table.NewRow();
row["MyImage"] = <Image byte array>;
tables.Rows.Add(row);
