Combining various attributes into a single column

In my TypeScript project, I am attempting to merge two properties into a single column. Is this achievable?

For instance, let's say I have properties named "Dog" and "Cat", and I would like to combine them into a shared column called "Animals" in the matTable.

Therefore, within a single cell of the "Animals" column, I aim to display "Dog, Cat".

Below is an example where I created two separate columns, but I am unsure how to display multiple properties in one cell:

configureColumns() {
    this.columns = [
      {
        key: "Dog",
        display: "Dog",
        styles: { flex: "0 0 10%" }
      },
      {
        key: "Cat",
        display: "Cat",
        styles: { flex: "0 0 10%" }
      },

Answer №1

Give this a shot:

let keysArray = columns.map(element => element.id).join(", ");
console.log(keysArray);

Answer №2

I successfully resolved my issue by utilizing the "value" attribute within the package:

{
        key: "DogCat",
        display: "Animals",
        styles: { flex: "0 0 25%"},
        value: (animal: AnimalDTO) => animal.Dog + ", " + animal.Cat
      }

This approach will provide me with the exact outcome I was seeking.

Special thanks to Oscar for the helpful response, it is greatly appreciated.
