Parameterizing a column name

[ColinBurrows]

I am trying to pass in a fieldname as a parameter to a function.
Within the function I need to filter a table using Table.SelectRows(table, each fieldname = something)
The problem I'm having is that no matter what I do, fieldname is always surrounded by double quotes so nothing gets returned.
Any ideas?
Thanks

Try

(tablename as table, fieldname as text) as table =>
let
    Result = Table.SelectRows(tablename, each Table.Column(_, fieldname) = something)
in
    Result

Remark: typically a table column would be passed to a function with type list (fieldname as list), but then you get a list with the fieldvalues, which can't be used as a reference within the Tabe.SelectRows function.

Many thanks. That works. Am still learning as I go and hadn't seen the Table.Column function.
Much appreciated.
