Add "sub-total" to my-account/orders table - woocommerce

Question

Trying to add the order subtotal in woocommerce my-account/orders table but I can't seem to get it to display. Currently it adds the column and the label but its not displaying the orders sub total. I am currently using the code below :
add_filter( 'woocommerce_account_orders_columns',
'add_account_orders_column', 10, 1 );
function add_account_orders_column( $columns ){
$columns['item_subtotal_tax_excl'] = __( 'Sub-total', 'woocommerce' );
return $columns;
}
add_action( 'woocommerce_my_account_my_orders_column_custom-column',
'add_account_orders_column_rows' );
function add_account_orders_column_rows( $order ) {
// Example with a custom field
if ( $value = $order->get_meta( 'item_subtotal_tax_excl' ) ) {
echo esc_html( $value );
}
}

Answer 1

Subtotal like in cart doesn't exist in WooCommerce Orders meta data, so you need to get it and calculate it from order items:
add_filter( 'woocommerce_account_orders_columns', 'add_account_orders_column', 10, 1 );
function add_account_orders_column( $columns ){
$columns['item_subtotal_tax_excl'] = __( 'Sub-total', 'woocommerce' );
return $columns;
}
add_action( 'woocommerce_my_account_my_orders_column_custom-column', 'display_account_orders_column_rows_value' );
function display_account_orders_column_rows_value( $order ) {
$subtotal = 0; // Initializing
// Loop through order items (line items)
foreach ( $order->get_items() as $item ) {
// Sum item subtotal excluding taxes and not discounted
$subtotal += $item->get_subtotal();
}
echo $subtotal;
}
Code goes in functions.php file of your active child theme (or active theme). Tested and works.

Edit: the following code worked for me: (answer provided by helgatheviking on woocommerce slack)
//show sub total in order page
add_filter( 'woocommerce_account_orders_columns',
'add_account_orders_column', 10, 1 );
function add_account_orders_column( $columns ){
$columns['item_subtotal_tax_excl'] = __( 'Sub-Total',
'woocommerce' );
return $columns;
}
add_action(
'woocommerce_my_account_my_orders_column_item_subtotal_tax_excl',
'add_account_orders_column_rows' );
function add_account_orders_column_rows( $order ) {
// Example with a custom field
if ( $value = $order->get_subtotal() ) {
echo esc_html( $value );
}
}
