Format Table Colors in PowerShell

21 February 2017 Ahmad IT, Microsoft, PowerShell
Did anyone think of formatting the output table as result of array of Objects/PSObjects on PowerShel

Did anyone think of formatting the output table as result of array of Objects/PSObjects on PowerShell host window with more fancy coloring?
I wonder if any imagine if we can change the fore color or the back color of the headers rather than the body (rows) colors?
What about formatting the table to have the odd rows with different fore/back colors rather than the even ones?
What about putting different separator line for the header the dashed one? Or, what about just remove it, or color it with different fore/back color?
What about putting separators between rows? And what if we can put those separators with different fore/back colors?
What about presenting the values for specific columns/properties with different fore/back colors?
What about some conditional formatting such as color specific values/cells when the values matches specific queries? Or what about color some values based on some complicated composite queries applies on multiple properties?

I had built my crazy PowerShell function “Write-PSObject” (pipeline supported) which can achieve all the imaginations and so much more with combination of over than 30 parameters which they can be used together or separately wisely to format your results with more fancy meaningful colors (fore/back).

N/A

02

 MatchMethod MM, M String[] False The array of values validations way which must be provided with one of the three valid set "Exact", "Match" or "Query". N/A N/A If this parameter not provided, the conditional formatting will not be functional and all the tailed parameters will be ignored. This must be tailed with the following parameters to be functional: "Column", "Value" and one or more of the following parameters: "ValueForeColor", "ValueBackColor", "RowForeColor" and/or "RowBackColor". N/A

03

FormatTableColor

FTC, FT, F

Switch

False

If specified, lines will be formatted with specified fore/back colors based on the sequence.

User can define specific fore or/and back color for odd lines in sequence, and different fore or/and back colors for even lines.

N/A

N/A

User needs to use one or more of the following parameters with this switch in order to make it functional:

 Column C, Col String[] False The list of the names of columns/properties which hold the value(s) to be validated to apply the table formatting. * N/A This parameter can provided as one string or array of them which must match the same count of the "Value" parameter or the script will be terminated (If the "$IgnoreErrors" switch is provided, the function will not be terminated, but the formatting will not be functional).   If the parameter "MatchMethod" is not provided, this column and all the other relative ones will be ignored and the whole conditional formatting will not be functional.   The "*" is referring to all the columns/properties within the table/PSObject(s). If the "*" is provided as a name of column/property, that means the same condition defined by the "MatchMethod" and "Value" parameters will be applied on all the columns/properties. For example, you can just mention "*" as column/property name to color all the "False" values for any column/property with  forecolor "Red" and/or backcolor "Black". MatchMethod

Examples:

I had created a sample data in XML text format which you need to run it first to apply all the following examples on it, or you can download the full script with all the attached examples from here.

The examples would be divided into two categories; the general formatting and the conditional formatting.

A. General Formatting

(Does not rely on specific conditions)

Example 01

Display the input object as it is without any formatting (Would act exactly as Write-Output).

Write-PSObject -object $servers;
# ----- Or -----
Write-PSObject $servers;
# ----- Or -----
$servers | Write-PSObject; #Pipeline supported.

 

Example 02

Display the body rows/lines (values) only.

Write-PSObject -Object $servers -BodyOnly;
# ----- Or -----
Write-PSObject $servers -BodyOnly;
# ----- Or -----
$servers | Write-PSObject -BodyOnly; #Pipeline supported.

Example 03

Display the Headers only.

Write-PSObject $servers -HeadersOnly;

 

Example 04

Display the Headers only and remove the header separator line (display only row/line which displays the columns/properties name).

Write-PSObject $servers -HeadersOnly -RemoveHeadersSeparator;

Example 05

Display the Headers with White forecolor, and, Blue background color. And the body rows/lines (values) with Yellow forecolor, and, DarkRed background color.

Write-PSObject $servers -BodyForeColor Yellow -BodyBackColor DarkRed -HeadersForeColor White -HeadersBackColor Blue;

Example 06

Display the input object as formatted table which displays each row/line in odd sequence (starting with the first body row) with "Cyan" forecolor.
Also, display each row/line in even sequence (starting with the second body row) with "Yellow" Fore Color.

Write-PSObject $servers -FormatTableColor -OddRowForeColor Cyan -EvenRowForeColor Yellow;

Example 07

Display the input object as formatted table which displays each row/line in odd sequence (starting with the first body row) with "DarkRed" background color.
Also, display each row/line in even sequence (starting with the second body row) with "Blue" background color.

Write-PSObject $servers -FormatTableColor -OddRowBackColor DarkRed -EvenRowBackColor Blue;

Example 08

Display the input object as formatted table which displays each row/line in odd sequence (starting with the first body row) with "Black" forecolor and White background color..
Also, display each row/line in even sequence (starting with the second body row) with "Yellow" Fore Color and Blue background color.

Write-PSObject $servers -FormatTableColor -OddRowForeColor Black -OddRowBackColor White -EvenRowForeColor Yellow -EvenRowBackColor Blue;

Example 09

Display the table with new linefeed between values/body rows/lines.

Write-PSObject $servers -InjectRowsSeparator;

Example 10

Display the table with new line of underscore characters ("_") between the values/body rows/lines.

Write-PSObject $servers -InjectRowsSeparator -RowsSeparator "_";

Example 11

Display the table with new dotted line between the values/body rows/lines with forecolor "Cyan".

Write-PSObject $servers -InjectRowsSeparator -RowsSeparator "." -RowsSeparatorForeColor Cyan;

Example 12

Display the table with new line of white spaces (" ") between the values/body rows/lines with background color "White".

Write-PSObject $servers -InjectRowsSeparator -RowsSeparator " " -RowsSeparatorBackColor White;

Example 13

Display the table with new line of combination of characters ("=*=.-^*") between the values/body rows/lines with forecolor "Black" and background color "White".

Write-PSObject $servers -InjectRowsSeparator -RowsSeparator "=*=.-^*" -RowsSeparatorForeColor Black -RowsSeparatorBackColor White;

Example 14

Replace the headers separator line/row (dashed line) with the equal character ("=") instead of the hyphen character ("-") with fore color Black, background color "Yellow".

Write-PSObject $servers -HeadersSeparator "=" -HeadersSeparatorForeColor Black -HeadersSeparatorBackColor Yellow;

Example 15

Display the table after forcing resizing the host PowerShell Window and changing the whole host forecolor (Green) and background color (Black).

Write-PSObject $servers -HostWindowWidth 150 -HostWindowHeight 50 -HostWindowForeColor Green -HostWindowBackColor Black;

Example 16

Display the values of the column/property "SN" with "Blue" forecolor and the values column/property "CPUCores" with "Yellow" forecolor.

Write-PSObject $servers -HostWindowWidth 150 -HostWindowHeight 50 -HostWindowForeColor Green -HostWindowBackColor Black;

Those samples were just few of what the function can do!
You can mix many samples together by mixing the parameters to get more fancy colorful results.
If those samples are not enough to help you to build your own color formatting, please check the parameters table above, or feel free to leave a message/comment for me, and I will reply as soon as possible.

    Getting this error on PSVersion 4.0...Write-Host : Cannot process the color because -1 is not a valid color.

      Hi, usually we get this error when you try to run your code on the ISE. Nevertheless, this should have been handled already which could mean a bug in the script. Could you please support me with the line of code you used to check this? Also, could you confirm if you are using the ISE not the console?

      Thanks a lot.

      Best Regards,
      Ahmad
