so please have a look at my code and tell me how could i remove blue color from first row?

here is the full code

Answer 1

Try this to give background color to cells.

 xlWorkSheet.Cells[iRowCounter, iColCounter].Interior.Color =
 System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);  

This one is for excel table.

Answer 2

I think, you should adding this code.

oShape.Table.Cell(row, 1).Shape.Fill.Visible = MsoTriState.msoTrue;
oShape.Table.Cell(row, 1).Shape.Fill.ForeColor.RGB = System.Drawing.Color.FromArgb(255, 255, 255).ToArgb();
