Listing Column Widths in Excel

I hacked Box Spout to support column widths formatting, but wanted a quick way of adding appropriate column widths (yes, automatic width determination would be better … but I didn’t want to spend hours sorting that). Instead of wasting time on automatic column widths, I wrote a simple Excel code module to tell me the appropriate column widths. If your data width might vary, you can add some padding to the ReportColumnWidth function. My data, fortunately, is fixed width.

Function iCeiling(iInput)
    iCeiling = Int(iInput)
    If iCeiling <> iInput Then
        iCeiling = Int(iInput) + 1
    End If
End Function

Function ReportColumnWidth(CellID As Range) As Double
 Application.Volatile
 ReportColumnWidth = iCeiling(CellID.ColumnWidth)
End Function

In Excel, use the ReportColumnWidth function to print the width of a column into a cell. This is my row #3.

In row #2, I have a counter that provides the row number for use in Box Spout. Row #4 creates the line needed to set the column width in my code using the concat function.

=CONCAT("$writer->setColumnsWidth(",A3,",",A2,",",A2,");")

Replacing the tab characters with newlines, I now have column widths set based on my data.
