Text placed within a specific length width

Text placed within a specific length width

[Heime]

I have added text in a named buffer using insert.      

(insert " Line Wrap     ")
(insert " Karl Koch     ")
(insert " Microsk Spez  ")

I would like to have an elisp function that inserts text inside a a string
of a specific size to avoid having to introduce leading or trailing spaces.  

Thus something like this for text of width 15

(insert-w "Line Wrap" 15)
(insert-w "Karl Koch" 15)
(insert-w "Microsk Spez" 15)

`string-pad' pads a string to particular length:
        (string-pad "Karl Koch" 15)
returns
        "Karl Koch      "

See describe-function for details

I can pad at back.  Is there other tool to pad at front ?

(string-pad STRING LENGTH &optional PADDING START)

You can use the argument "START"

(string-pad "Test" 15 nil t)
returns
"           Test"
