Add a custom column to My Account Orders table in Woocommerce 3+

This requires 2 functions that will add a new column

The second function hook is a composite hook: woocommerce_my_account_my_orders_column_{$column_id} where {$column_id} need to be replaced by the column key slug that is set in the first function.

That second function manage the displayed row values and you can add for example a custom field to get custom order meta data values.

The code:

add_filter( 'woocommerce_account_orders_columns', 'add_account_orders_column', 10, 1 );function add_account_orders_column( $columns ){    $columns['custom-column'] = __( 'New Column', '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( '_custom_field' ) ) {        echo esc_html( $value );    }}

Code goes in function.php file of your active child theme (or active theme). Tested and works.

You are done and have added a custom column to My account orders table:

If you which to make changes in the table html output, you will have to override the template file: myaccount/orders.php

If you don't wanna change the order template under myaccount page. Here's what you have to do.

First:

function wc_add_myaccount_order_column( $columns ) {    $columns[ 'custom-column' ] = __( 'Custom Column', 'woocommerce' );}add_filter( 'woocommerce_my_account_my_orders_columns', 'wc_add_myaccount_order_column' );

Second:

function wc_custom_column_display( $order ) {    // do something here    echo "testing";}add_action( 'woocommerce_my_account_my_orders_column_custom-column', 'wc_custom_column_display' );

The code above will display "testing" in each order under "Custom Column" column.

Note: If you actually wanna change the entire template, like the design for example. You can follow the first answer above.

Just to improve the accepted answer I add a line to choose the position of the column (after total):

function sv_wc_add_my_account_orders_column( $columns ) {    $new_columns = array();    foreach ( $columns as $key => $name ) {        $new_columns[ $key ] = $name;        // add ship-to after order status column        if ( 'order-total' === $key ) {  //this is the line!            $new_columns['custom-column'] = __( 'Custom Column', 'woocommerce' );        }    }    return $new_columns;}add_filter( 'woocommerce_my_account_my_orders_columns', 'sv_wc_add_my_account_orders_column' );    function wc_custom_column_display( $order ) {        // do something here        echo "testing";    }    add_action( 'woocommerce_my_account_my_orders_column_custom-column', 'wc_custom_column_display' );
