Happy new year, my best wishes and thanks for this awesome web component.
I’m using Smart.Table (web component) with Svelte. I have different languages and would like to know how to update just columns without affecting the rest.
In particularly, I want to translate columns label when the user switch language. Here is my code:
```
  import { _ } from 'svelte-i18n'
  import { onMount } from 'svelte'
  import 'smart-webcomponents/source/styles/smart.default.css'
  import 'smart-webcomponents/source/modules/smart.table.js'
  export let fields = []
  export let source = []
  onMount(() => {
    const columns = fields.map(field => {
      const f = field.split(':') // field = 'name: string'
      return {
        label: $_(f[0]), // translate
        dataField: f[0],
        dataType: f[1].trim()
      }
    })
    Smart('#table', class {
      get properties() {
        return {
          keyboardNavigation: true,
          filtering: true,
          sortMode: 'one',
          selection: true,
          paging: true,
          freezeHeader: true,
          virtualization: true,
          dataSource: new Smart.DataAdapter({
            dataSource: source, dataFields: fields }),
          columns
        }
      }
    })
  })
```
Right now I’m doing it when I render the component because I couldn’t find any function to update just column labels.
Any help will be really appreciated. Thank you so much in advance for your time and knowledge!

Hi Johnny,
Happy New Year best wishes from Smart UI Team!
There is a way that you can access the column headers properties and change them according to your needs.
I have made a code snippet for you to showcase one way of doing this:
<script>
let clickHandler = function(){
const table = document.getElementById(‘table’)
table.columns = [
{ label: ‘ID your language’, dataField: ‘id’, dataType: ‘number’ },
{ label: ‘Name in Another Language’, dataField: ‘firstName’, dataType: ‘string’ },
{ label: ‘Last Name in Another Language’, dataField: ‘lastName’, dataType: ‘string’ },
{ label: ‘Product Name in Another Language’, dataField: ‘productName’, dataType: ‘string’ },
{ label: ‘Qunatity in Another Language’, dataField: ‘quantity’, dataType: ‘number’ }
]
console.log(‘Column Headers Changed’)
}
</script>
<body>
<smart-table id=”table”></smart-table>
<button onclick=”clickHandler()”>Click Me</button>
</body>
Please, do not hesitate to contact us if you have any additional questions.
Best regards,

Thank you so much Yavor, it works like a charm with Svelte! One of the best web components collection out there!
I’m using: bind:this={table}
Best regards and enjoy the weekend !!
