    "Harjumaa",
    "Tallinn",
    "Lastekodu",
    "24"
]

Answer 1

你可以使用 mv-apply + make_list_if():

datatable(value:dynamic)
[
    dynamic([
        "",
         "Harjumaa",
         "Tallinn",
         "Lastekodu",
         "24",
         ""
    ]), 
]
| mv-apply value on (
    summarize value = make_list_if(value, isnotempty(value))
)

value
[ "Harjumaa", "Tallinn", "Lastekodu", "24" ]
