How to add a custom width to a p-column in PrimeNG within an Angular HTML template

I am trying to assign unique widths to each column in my columns using [style] based on the example given. I attempted to use

[style]="{'width.px':'column.length + 10'}"

, but unfortunately, 'column.length' isn't functioning properly in the template. Below is an example of my template:

<p-column *ngFor="let column of columns"
        [field]="column"
        [header]="label[column] ? label[column] : column"
        [style]="{'width.px':'column.length + 10'}"></p-column>

Any advice or assistance with this would be greatly appreciated. Thanks.

It's generally not recommended to include numerous evaluations within the template:

A more efficient approach is to handle mapping and calculations within your component, assuming you have an array of objects called columns. By mapping through this array and adding a new property called columnWidth, you can perform your evaluations there.

// Assuming you have an array of objects.
var columns = [
  {
    id: 1
  },
  {
    id: 2
  },
  {
    id: 3
  }
];

var columnWithExtraProperty = columns.map((column) => {
  return{
    ...column,
    columnWidth: column.length + 10 + 'px'
  }
});

// console.log(columnWithExtraProperty);

After implementing the above in your component, you can then use the following code snippet in your template:

<p-column *ngFor="let column of columnWithExtraProperty"
  [field]="column"
  [header]="label[column] ? label[column] : column"
  [style]="{'width.px':column.columnWidth}"></p-column>

After some trial and error, I came up with a workaround that seems to address the issue at hand:

[style]="{'width.px': +(column.length)+20}"

By adding a '+' sign before the column length, I was able to ensure it was treated as a number rather than a string. Attempting to use Number(column) did not yield the desired result in this case, which was unexpected. It appears that column.length is expected to be numerical, hence the need for the additional 20 pixels to margin the text.
