I have written below piece of code to change background color of table cell of ppt using c# code but nothing is happening:

//creating powerpoint aaplication
PowerPoint.Application pptApp = new PowerPoint.Application();
pptApp.Visible = Office.MsoTriState.msoTrue;
var pptPresent = pptApp.Presentations;
var fileOpen = pptPresent.Open(@file, Office.MsoTriState.msoFalse, Office.MsoTriState.msoTrue, Office.MsoTriState.msoTrue);
// getting first slide
PowerPoint.Slide objSlide = fileOpen.Slides[1];
PowerPoint.Shapes item = objSlide.Shapes;
// getting first shape
var shape1 = item[1];
// check if shape is table
if (shape1.HasTable == Office.MsoTriState.msoTrue)
{
    // change the table cell to red color
    shape1.Table.Cell(2, 5).Shape.Fill.BackColor.RGB = System.Drawing.Color.Red.ToArgb();
    // make it visible
    shape1.Fill.Visible = Office.MsoTriState.msoTrue;
}
// saving the ppt
fileOpen.SaveAs(openFolder + subStr + ".pptx",PowerPoint.PpSaveAsFileType.ppSaveAsDefault,Office.MsoTriState.msoTrue);
// close the ppt
fileOpen.Close();

Above piece of code is not working as expected, can someone help me?

To change the cell color ForeColor needs to be used instead of BackColor. Drawing colors may not work as expected. To change that use ColorTranslator. 

shape1.Table.Cell(2, 5).Shape.Fill.ForeColor.RGB = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

Great question! The Fill property is also available for the Shape object, wether it's a Cell or a another type of Shape.

Another example for the Fill property is mentioned in this thread: https://stackoverflow.com/a/26253177/20337158.

Also from the Microsoft learning sites: https://learn.microsoft.com/en-us/previous-versions/office/office-12/ff763049(v=office.12)
