powershell - Pipline behavior of Format-Table -

i have trouble understand pipline behavior in powershell.

i want output table grows @ every return in script. of course works myfunction | format-table want set width. works in powershell ise.

• powershell ise: output @ every return of main
• powershell: returns output @ end

powershell code:

myfunction | format-table @{label="prop1"; expression={$_.prop1};width=10},                       @{label="prop2"; expression={$_.prop2};width=14},                       @{label="prop3"; expression={$_.prop3};width=10} 

• powershell ise: output @ every return of main
• powershell: output @ every return of main

powershell code:

myfunction | format-table  

• powershell ise: returns output @ end
• powershell: returns output @ end

powershell code:

myfunction | format-table -autosizre
