不能直接指向。displayProperty只能指向一个属性。但是，您可以创建一个新属性，将API响应中的字段值连接在一起，并将其用作displayProperty。例如：

let LocationSchema = coda.makeObjectSchema({
  properties: {
    city: { type: coda.ValueType.String },
    state: { type: coda.ValueType.String },
    // Add an additional property to use as the display value.
    display: { type: coda.ValueType.String },
    // ...
  },
  displayProperty: "display",
  // ...
});

pack.addFormula({
  // ...
  resultType: coda.ValueType.Object,
  schema: LocationSchema,
  execute: async function([], context) {
    let location = await fetchLocationFromAPI(context);
    return {
      city: location.city,
      state: location.state,
      // Populate the display value using data from the API.
      display: location.city + ", " + location.state,
    },
  },
});
