C＃：如何從以編程方式在Power Point中創建的表中刪除第一行顏色

Question

我試圖在Powerpoint幻燈片中以編程方式創建具有兩列和許多行的表，最后我可以做到這一點，但是當我打開Power Point幻燈片時，我注意到我的表的第一行是藍色，但是在我的代碼中我沒有提到任何顏色為表。

所以請看一下我的代碼，告訴我如何從第一行中刪除藍色？

這是完整的代碼

嘗試使用此項為單元格賦予背景色。

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

這是一張用於excel表的文件。

我認為，您應該添加此代碼。

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();
