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 -Column 5 -NumberFormat 'Currency'
$ws contains a worksheet object - and column E is set to use the local currecy format.
Intelisense will complete predefined number formats. Expand-NumberFormat currency will show you how currency is interpreted on the local computer.
.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
.EXAMPLE
C:\> Set-Column -Worksheet $ws -Heading "Link" -Value {"https://en.wikipedia.org" + $worksheet.cells["B$Row"].value } -AutoSize
In this example, the worksheet in $ws has partial links to wikipedia pages in column B.
Value is is a script block and it outputs a string which begins https... and ends with the value of cell at column B in the current row.
When given a valid URI set-Column makes it a hyperlink The column will be autosized to fit the links.
