        {  
            string docName = @"C:\Users\Public\Documents\ColumnEx.xlsx";  
            string worksheetName = "Sheet1";

            // Open the document as read-only.  
            using (SpreadsheetDocument document = SpreadsheetDocument.Open(docName, false))

                    .WorkbookPart.GetPartById(sheets.First().Id);  

                // Get the column name for the specified cell.  
                // Create a regular expression to match the column name portion of the cell name.  
                Regex regex = new Regex("[A-Za-z]+");  
                Match match = regex.Match(cellName);  
                Console.WriteLine("{0} {1}","The column is:", match.Value);

col (Column Width & Formatting)

Defines column width and column formatting for one or more columns of the worksheet.

[Example:This example shows that column 5 (E) has width and style information applied.

<col min="5" max="5" width="9.140625" style="3"/>  

end example]

cols (§18.3.1.17)

Attributes	Description
bestFit (Best Fit Column Width)	Flag indicating if the specified column(s) is set to 'best fit'. 'Best fit' is set to true under these conditions: - The column width has never been manually set by the user, - The column width is not the default width - 'Best fit' means that when numbers are typed into a cell contained in a 'best fit' column, the column width should automatically resize to display the number. [Note: In best fit cases, column width must not be made smaller, only larger. end note] The possible values for this attribute are defined by the W3C XML Schema boolean datatype.
collapsed (Collapsed)	Flag indicating if the outlining of the affected column(s) is in the collapsed state. See description of row collapsed and outlinePr element's summaryBelow and summaryRight attributes for detailed information. The possible values for this attribute are defined by the W3C XML Schema boolean datatype.
customWidth (Custom Width)	Flag indicating that the column width for the affected column(s) is different from the default or has been manually set. The possible values for this attribute are defined by the W3C XML Schema boolean datatype.
hidden (Hidden Columns)	Flag indicating if the affected column(s) are hidden on this worksheet. The possible values for this attribute are defined by the W3C XML Schema boolean datatype.
max (Maximum Column)	Last column affected by this 'column info' record. The possible values for this attribute are defined by the W3C XML Schema unsignedInt datatype.
min (Minimum Column)	First column affected by this 'column info' record. The possible values for this attribute are defined by the W3C XML Schema unsignedInt datatype.
outlineLevel (Outline Level)	Outline level of affected column(s). Range is 0 to 7. See description of outlinePr element's summaryBelow and summaryRight attributes for detailed information. The possible values for this attribute are defined by the W3C XML Schema unsignedByte datatype.
phonetic (Show Phonetic Information)	Flag indicating if the phonetic information should be displayed by default for the affected column(s) of the worksheet. The possible values for this attribute are defined by the W3C XML Schema boolean datatype.
style (Style)	Default style for the affected column(s). Affects cells not yet allocated in the column(s). In other words, this style applies to new columns. The possible values for this attribute are defined by the W3C XML Schema unsignedInt datatype.
width (Column Width)	Column width measured as the number of characters of the maximum digit width of the numbers 0, 1, 2, …, 9 as rendered in the normal style's font. There are 4 pixels of margin padding (two on each side), plus 1 pixel padding for the gridlines. width = Truncate([{Number of Characters} * {Maximum Digit Width} + {5 pixel padding}]/{Maximum Digit Width}*256)/256 [Example: Using the Calibri font as an example, the maximum digit width of 11 point font size is 7 pixels (at 96 dpi). In fact, each digit is the same width for this font. Therefore, if the cell width is 8 characters wide, the value of this attribute must be Truncate([8*7+5]/7*256)/256 = 8.7109375. end example] To translate the value of width in the file into the column width value at runtime (expressed in terms of pixels), use this calculation: =Truncate(((256 * {width} + Truncate(128/{Maximum Digit Width}))/256)*{Maximum Digit Width}) [Example: Using the same example as above, the calculation would be Truncate(((256*8.7109375+Truncate(128/7))/256)*7) = 61 pixels. end example] To translate from pixels to character width, use this calculation: =Truncate(({pixels}-5)/{Maximum Digit Width} * 100+0.5)/100 [Example: Using the example above, the calculation would be Truncate((61-5)/7*100+0.5)/100 = 8 characters. end example] [Note: when wide borders are applied, part of the left/right border must overlap with the 2 pixel padding on each side. Wide borders do not affect the width calculation of the column. end note] [Note: When the sheet is in the mode to view formulas instead of values, the pixel width of the column is doubled. end note] The possible values for this attribute are defined by the W3C XML Schema double datatype.

[Note: The W3C XML Schema definition of this element’s content model (CT_Col) is located in §A.2. end note]
