request: async params => {
console.log(params)
const result = await fetchData({ name: params.keyWords || '' })

return result?.map(({ id: value, name: label }) => {
return { label, value }
})
},
defaultKeyWords: '',

Start with the ProTable column handling for valueType:'select' fields that use request, using the linked CodeSandbox to reproduce the behavior. Trace the request triggered during search and selection, then verify that selecting a value no longer causes an additional request.
