Creating a column based on the value of a filtered table

Hello everyone, I'm looking to create a new column that will extract values from a different table within my queries. Essentially, I have a table X with a column containing IDs, a column with dates ...

    Hi Gp2024, your request is confusing. Maybe you want this but there is no [ID] connection between your tables. I've filtered [pfg_codban] = 4 at last step.

    let
    TableX = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("jc5BDsAgCATAv3g2KVAUeIvx/9+oJE206KHcyGSz21oCP0o5AV7AFwHxeERFUs8vc2RULZMxMnO9dxZnb6qH7BE5IpnaZIpsYuU367raWXBvNkffiExTZdO88qfY2dgG9wc=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [pfg_codban = _t, pfg_inivig = _t, pfg_valor = _t]),
    ChangedTypeTableX = Table.TransformColumnTypes(TableX,{{"pfg_codban", Int64.Type}, {"pfg_inivig", type date}}, "sk-SK"),

Apologies for any confusion. Let me clarify. I want to check if the data in the column [pfg_inivig] falls between the values in columns [dt_inicio_vigencia] and [dt_fim_vigencia]. If it does, I need to retrieve the first value from the column [pfg_valor] and add it to a new column in table Y called [te_bAm].
