You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: sort.rs
    path of file: ./repos/Daft/src/daft-table/src/ops
    
    the code of the file until where you have to start completion: use crate::Table;
use common_error::{DaftError, DaftResult};
use daft_core::Series;
use daft_dsl::Expr;

impl Table {
    pub fn sort(&self, sort_keys: &[Expr], descending: &[bool]) -> DaftResult<Table> {
        let argsort = self.argsort(sort_keys, descending)?;
        self.take(&argsort)
    }

    pub fn argsort(&self, sort_keys: &[Expr], descending: &[boo
    
    pub fn argsort(&self, sort_keys: &[Expr], descending: &[bool]) -> DaftResult<Series> {
        if sort_keys.len() != descending.len() {
            return Err(DaftError::ValueError(format!(
                "sort_keys and descending length must match, got {} vs {}",
                sort_keys.len(),
                descending.len()
            )));
        }
        if sort_keys.len() == 1 {
            self.eval_expression(sort_keys.get(0).unwrap())?
                .argsort(*descending.first().unwrap())
        } else {
            let expr_result = self.eval_expression_list(sort_keys)?;
            Series::argsort_multikey(expr_result.columns.as_slice(), descending)
        }
    }
