Function Set-Column { <# .SYNOPSIS Adds a column to the existing data area in an Excel sheet, fills values and sets formatting .DESCRIPTION Set-Column takes a value which is either string containing a value or formula or a scriptblock which evaluates to a string, and optionally a column number and fills that value down the column. A column name can be specified and the new column can be made a named range. The column can be formatted. .Example C:> Set-Column -Worksheet $ws -Heading "WinsToFastLaps" -Value {"=E$row/C$row"} -Column 7 -AutoSize -AutoNameRange Here $WS already contains a worksheet which contains counts of races won and fastest laps recorded by racing drivers (in columns C and E) Set-Column specifies that Column 7 should have a heading of "WinsToFastLaps" and the data cells should contain =E2/C2 , =E3/C3 the data cells should become a named range, which will also be "WinsToFastLaps" the column width will be set automatically #> [cmdletbinding()] Param ( [Parameter(ParameterSetName="Package",Mandatory=$true)] [OfficeOpenXml.ExcelPackage]$ExcelPackage, #The sheet to update can be a given as a name or an Excel Worksheet object - this sets it by name [Parameter(ParameterSetName="Package")] #The sheet to update can be a given as a name or an Excel Worksheet object - $workSheet contains the object [String]$Worksheetname = "Sheet1", [Parameter(ParameterSetName="sheet",Mandatory=$true)] [OfficeOpenXml.ExcelWorksheet]$Worksheet, #Column to fill down - first column is 1. 0 will be interpreted as first unused column [ValidateRange(0,16384)] $Column = 0 , #First row to fill data in [ValidateRange(1,1048576)] [Int]$StartRow , #value, formula or script block to fill in.
