可以使用对象字面量和数组的解构来简化这段代码：

const fieldMap = {
  order_no: 'column_head_order_no',
  old_order_code: 'column_old_order_code',
  customer_name: 'column_customer_name',
  memo: 'column_head_memo',
  order_date: 'column_order_date',
  sum_tax_amount: 'column_sum_tax_amount',
  creator: 'column_creator',
  customer_tax_id: 'column_customer_tax_id',
  customer_address: 'column_customer_address',
  customer_tel: 'column_customer_tel',
  customer_bank: 'column_customer_bank',
  customer_bank_account: 'column_customer_bank_account',
  customer_email: 'column_customer_email',
  org_name: 'column_org_name'
}

const columns = {}
advanceConfig.value.apiKingdeeDetailTableSetting.mainTableField.forEach(item => {
  if (fieldMap[item.name]) {
    columns[fieldMap[item.name]] = item.field_name
  }
})

这样可以去除大量的重复代码，同时也更加易读和易于维护。
