Question

我试图在电源点幻灯片中以编程方式创建具有两列和多行的表格，最后我可以做到但是当我打开电源点幻灯片然后我注意到我的表格第一行有蓝色但在我的代码中我无处可去提及桌子的任何颜色。

所以，请查看我的代码并告诉我如何从第一行中删除蓝色？

这里是完整代码

Answer 1

尝试此操作为细胞提供背景颜色。

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

这个是excel表。

Answer 2

我想，您应该添加此代码。

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();
