Formula is not calculated

[tudorels]

I use vue 3 and I have a simple table config:
const options = ref({
columnSorting:false,
defaultColAlign:'left',
columns: [
{ type: 'text', title: 'Code', width: '100px', readOnly:true},
{ type: 'text', title: 'Description', width: '500px', readOnly:true},
{ type: 'dropdown', title: 'Width(mm)', width: '100px', source:[ 62, 86 ]},
{ type: 'numeric', title: 'Length(mm)', width: '100px'},
{ type: 'numeric', title: 'Heigth(mm)', width: '100px'},
{ type: 'numeric', title: 'Weigth(kg)', width: '100px', mask:'#.##,00', decimal:','},
{ type: 'numeric', title: 'Cost(€)', width: '100px', mask:'€ #.##,00', decimal:','},
{ type: 'text', title: 'Steel', width: '100px' }
],
});
The column cost is not calculated and I have the formula in the dataset '=ROUND(SUM(G1:G16), 2)'
Can you tell me if you have any ideea how to enable calculation? Am I doing something wrong?
Thank you!
