Declaring parameters in every case

Hello
I just started to play around HTML outputs in Powershell and when i read those cmdlets and parameters, my eyes are bleeding as yours will be. My point is that there are some parameters to combine some parameters but i couldn’t figure out how. I think that i shouldn’t declare parameters for every case.
Ps: and Yes, i copied some cmdlets from here but i am just learner.

Are you asking about the hash tables that this script is using to pass the parameters to the ConvertTo-EnhancedHTMLFragment cmdlet?

$params = @{
    'As'='Table';
    'PreContent'=' SERVIS LOGS';
    'MakeTableDynamic'=$true;
    'TableCssClass'='grid';
    'Properties'='DIsplayname','name',@{n='Service Status';e={$_.Status};css={if ($_.Status -eq "Stopped") { 'red' } else {'green'}}}
}
