How to display the category id along with category name on categories list?

Question

I have a categories and I have to display all categories id along with categories name.

Something like

Accessories(id=1)

featured(id=1)

OR

id  Name
1   Accessories
2   featured

Is it possible to display without a plugin?

You can add new column using below code. replace (your-texanomy) with your taxonomy slug. I have tested and its working fine. https://prnt.sc/qbibg0

#add header before category name
function taxonomy_custom_column_header( $columns ){

    $columns = array_slice($columns, 0, 1, true) +
    array("cat_id" => "ID") +
    array_slice($columns, 1, count($columns) - 1, true) ;

    return $columns;
}
add_filter( "manage_edit-(your-texanomy)_columns", 'taxonomy_custom_column_header', 10);

# add value to newly added column
function taxonomy_custom_column_content( $value, $column_name, $tax_id ){

    if ( 'cat_id' == $column_name ) {
        $content = $tax_id;
    }
    return $content;
}
add_action( "manage_(your-texanomy)_custom_column", 'taxonomy_custom_column_content', 10, 3);
