I am currently using PrimeNG table control with a frozen column feature.

Everything working fine and I am able to get frozen column but now I want to modify my frozen and unfrozen column styles and custom width of column for that I have used below property.

Code:

<p-table [columns]="scrollableCols" [frozenColumns]="frozenCols" [value]="cars" [scrollable]="true" scrollHeight="300px" frozenWidth="250px">
  <ng-template pTemplate="colgroup" let-columns>
    <colgroup>
      <col style="width:200px"> 
      <col style="width:50px">
      <col style="width:100px">
      <col style="width:100px"> 
      <col style="width:100px">
      <col style="width:100px">
    </colgroup>
  </ng-template>
  <ng-template pTemplate="header" let-columns>
    <tr>
      <th *ngFor="let col of columns">
        {{col.header}}
      </th>
    </tr>
  </ng-template>
  <ng-template pTemplate="body" let-rowData let-columns="columns">
    <tr>
      <td *ngFor="let col of columns">
        {{rowData[col.field]}}
      </td>
    </tr>
  </ng-template>
</p-table>

Output : enter image description here

by using width I am able to achieve width of my columns but for the first 2 columns, both froze & unfroze column table automatically taking the same width for all 2 columns I want to assign the different sizes of columns in both froze & unfroze column s.

is it possible to add different sizes for froze & unfroze columns?

All you need is pTemplate="frozencolgroup"

<ng-template pTemplate="frozencolgroup" let-columns>
        <colgroup>
            <col style="width:200px">
            <col style="width:50px">
        </colgroup>
    </ng-template>
    <ng-template pTemplate="colgroup" let-columns>
        <colgroup>
            <col style="width:100px">
            <col style="width:100px">
            <col style="width:100px">
            <col style="width:100px">
        </colgroup>
    </ng-template>

UPDATE: With scroll table can be broke row height. Below tip function to fix this

makeRowsSameHeight() {
    setTimeout(() => {
      if ($('.ui-table-scrollable-wrapper').length) {
        let wrapper = $('.ui-table-scrollable-wrapper');
        wrapper.each(function () {
          let w = $(this);
          let frozen_rows: any = w.find('.ui-table-frozen-view tr');
          let unfrozen_rows = w.find('.ui-table-unfrozen-view tr');
          for (let i = 0; i < frozen_rows.length; i++) {
            if (frozen_rows.eq(i).height() > unfrozen_rows.eq(i).height()) {
              unfrozen_rows.eq(i).height(frozen_rows.eq(i).height());
            } else if (frozen_rows.eq(i).height() < unfrozen_rows.eq(i).height()) {
              frozen_rows.eq(i).height(unfrozen_rows.eq(i).height());
            }
          }
        });
      }
    });
  }
