Can't convert a 'string' to a 'column' #2979
Description
ls | select name
let column_name = "name"; ls | select $column_name => this will not work. expected column path, found string
ls | get $(= name). => This will not work either
There's no way to convert a string to a column path. This makes it very difficult to manipulate a table from a script.
