C# code to format a certain range of Excel cells using the Format As Table button -- but from C# interop code
Sometimes, you have a range of cells and you want to choose the Format As Table button to format the cells as a nice table.

Here's how to do that using Excel interop:

C#
public void FormatAsTable(Excel.Range SourceRange, string TableName, string TableStyleName)
{
    SourceRange.Worksheet.ListObjects.Add(XlListObjectSourceType.xlSrcRange,
    SourceRange, System.Type.Missing, XlYesNoGuess.xlYes, System.Type.Missing).Name =
        TableName;
    SourceRange.Select();
    SourceRange.Worksheet.ListObjects[TableName].TableStyle = TableStyleName;
}


That's it! To apply a table style, e.g. TableStyleMedium15, to a range of cells, you say:

C#
Excel.Range SourceRange = (Excel.Range)oSheet.get_Range("A6","X10"); // or whatever range you want here
FormatAsTable(SourceRange, "Table1", "TableStyleMedium15");


The "Table1" is just a random name for the table; it's arbitrary, but every table you format must be a unique range. The table style names you can find out by recording a macro, applying the formatting by hand, and then reading off of the VBA module what style name Excel filled in once you've stopped the recording.

The movie showcases the Chandra X-ray Observatory, one of NASA’s four great observatories and the world’s most powerful telescopes for detecting X-rays. The movie has been accepted for screening at the U.S. Air Force Academy ("USAFA" for short) Planetarium and will highlight how scientists use clusters of galaxies, the largest bound objects in the Universe, to learn more about the formation and evolution of the cosmos --- as well as the space telescopes used for this purpose, and the stories of the astronauts who launched them and the scientists who went before Dr. Hart in learning more about the nature of the Universe.
