如何连接材料表反应中的两个或多个字段

Question

I'm trying to create a "Name" column in my material-table with concatenated firstname, lastname from my array, but It only accepts one data per field.

Any suggestion or help to make it possible?

const client = {
  firstname: "Tracy",
  lastname: "Santos",
  address: {
    address1: "Manila",
    address2: "Philippines",
  }
}

const columns = [
  { title: 'Name', field: 'client.firstname' + ' ' + 'client.lastname' },
  { title: 'Address', field: 'client.address.address1' + ' ' + 'client.address.address2' },
]

<MaterialTable
  column={ columns }
  data={ client }
/>

Answer 1

An alternate approach that doesn't require modifying the data you pass to the table would be to use a custom render function for that field.

{
  render: (client) => {
    return `${client.firstName} ${client.lastName}`;
  },
  title: 'Client',
},

Answer 2

Your columns need to have a field value that exists in the data object.

So, change your columns object to be:

const columns = [
  { title: 'Name', field: 'fullName' },
  { title: 'Address', field: 'fullAddress' },
];

Once you have the columns, you need to modify the data you pass into the component.

const client = {
  firstname: 'Tracy',
  lastname: 'Santos',
  address: {
    address1: 'Manila',
    address2: 'Philippines',
  }
}

// Create the new object
const newData = {
  fullName: `${client.firstname} ${client.lastname}`,
  fullAddress: `${client.address.address1}, ${client.address.address2}`,
};

Then, you can pass the data to the table:

<MaterialTable columns={columns} data={newData} />

---

note : I've used Template Literals here, because it's a little easier to read - but the code above is doing the following:

const newData = {
  fullName: client.firstname + ' ' + client.lastname,
  fullAddress: client.address.address1 + ', ' + client.address.address2,
};

The above answers will only work if there is no search required in the material-table, if the search is required then you will have to add "customFilterAndSearch" to the answer as below-

 const columns = [
        {
          title: 'Name',
          render: client => `${client.firstname} ${client.lastname}`,
          customFilterAndSearch: (term, client) => (client.firstname.toLowerCase() + ' ' + client.lastname.toLowerCase()).indexOf(term.toLowerCase()) !== -1
        }
      ]
