How to change column heading in WooCommerce "My account" orders table

How can I change the column header text in recent order table in WooCommerce?

See attached image

The myaccount/my-orders.php template file in my theme contains:

<?php
/**
 * My Orders - Deprecated
 *
 * @deprecated 2.6.0 this template file is no longer used. My Account shortcode uses orders.php.
 * @package WooCommerce\Templates
 */

defined( 'ABSPATH' ) || exit;

$my_orders_columns = apply_filters(
    'woocommerce_my_account_my_orders_columns',
    array(
        'order-number'  => esc_html__( 'Order', 'woocommerce' ),
        'order-date'    => esc_html__( 'Date', 'woocommerce' ),
        'order-status'  => esc_html__( 'Status', 'woocommerce' ),
        'order-total'   => esc_html__( 'Total', 'woocommerce' ),
        'order-actions' => '&nbsp;',
    )
);

$customer_orders = get_posts(
    apply_filters(
        'woocommerce_my_account_my_orders_query',
        array(
            'numberposts' => $order_count,
            'meta_key'    => '_customer_user',
            'meta_value'  => get_current_user_id(),
            'post_type'   => wc_get_order_types( 'view-orders' ),
            'post_status' => array_keys( wc_get_order_statuses() ),
        )
    )
);

if ( $customer_orders ) : ?>

Solution

As you can see at the top of the template file included in your question, it is deprecated since WooCommerce 2.6.0 and no longer used.

My Orders - Deprecated since 2.6.0. This template file is no longer used. My Account shortcode uses orders.php

If you then have a look at myaccount/orders.php and includes/wc-account-functions.php you will see it contains at line 186 - 206

/**
 * Get My Account > Orders columns.
 *
 * @since 2.6.0
 * @return array
 */
function wc_get_account_orders_columns() {
    $columns = apply_filters(
        'woocommerce_account_orders_columns',
        array(
            'order-number'  => __( 'Order', 'woocommerce' ),
            'order-date'    => __( 'Date', 'woocommerce' ),
            'order-status'  => __( 'Status', 'woocommerce' ),
            'order-total'   => __( 'Total', 'woocommerce' ),
            'order-actions' => __( 'Actions', 'woocommerce' ),
        )
    );

    // Deprecated filter since 2.6.0.
    return apply_filters( 'woocommerce_my_account_my_orders_columns', $columns );
}

So to answer your question:

Via the woocommerce_account_orders_columns filter hook you could apply this in the following way

function filter_woocommerce_account_orders_columns( $columns ) {
    // DEBUG: remove afterwards
    echo '<pre>', print_r( $columns, 1 ), '</pre>';
    
    $columns['order-number'] = __( 'New name 1', 'woocommerce' );
    $columns['order-date'] = __( 'New name 2', 'woocommerce' );
    $columns['order-status'] = __( 'New name 3', 'woocommerce' );
    $columns['order-total'] = __( 'New name 4', 'woocommerce' );
    $columns['order-actions'] = __( 'New name 5', 'woocommerce' );

    return $columns;
}
add_filter( 'woocommerce_account_orders_columns', 'filter_woocommerce_account_orders_columns', 10, 1 );
