Making table structure based on values in numeric array

[Heime]

I want to make a table structure in the following manner.

(setq my-table
      '(("Feature"      ""  ""  "")  ; header
        ("icomplt-horz" "xxxxx" "xxxxx" "xxxx")
        ("icompt-vert"  "xxxxx" "xxxxx" "")
        ("ivy"          "xxxxx" "xxxxx" "")
        ("vertico"      "xxxxx" "" "")
        ("helm"         "" "" "")))

But the number of "xxxxx" sections depends on an array "(setq selecrt [3 2 2 1 
0])".
each number associated with the completion framework starting with 
"icomplt-horz".

3 means three sets of "xxxxx", 2 means two sets of "xxxxx", and so on.
