Exploring Knockout's foreach binding with nested table structures

I find myself in a rather unique situation and I am looking to see if knockout js can help me solve it.

Here is the setup:

Order = function() {
    var self = this;
    self.Name = 'default';
}

Customer = function() {
     var self = this;
     self.Name = 'default';
     self.Orders = [];
}

Currently, I have a table like this:

<table>
    <thead>
        <tr>
            <th>Customer Name</th>
        </tr>
    </thead>
    <tbody data-bind="foreach: CustomerArray">
        <tr>
            <td data-bind="text: Name"></td>
        </tr>
    </tbody>
</table>

This displays a list of customer names, which is great.

Now, for my next step, I need to format the table in such a way that it lists the Order Name first, followed by the Customer Name at the bottom:

Customer Name (TH LABEL)
Order1
Order2
Order3
Smith, Frank

I thought about nesting my order array within each customer iteration with a tbody, but I don't like this approach because the column widths won't align since they are separate tables.

Is there a better solution out there to tackle this peculiar problem?

Thank you!

Answer №1

If you want to display a TD for each order along with the customer's name without using a containing element, you could utilize the "containerless control flow syntax" as mentioned in Note 4 on the foreach docs page.

<table>
    <thead>
        <tr>
            <th>Customer Name</th>
        </tr>
    </thead>
    <tbody data-bind="foreach: CustomerArray">
        <!-- ko foreach: Orders -->
        <tr>
            <td data-bind="text: OrderDetails"></td>
        </tr>
        <!-- /ko -->
        <tr>
            <td data-bind="text: Name"></td>
        </tr>
    </tbody>
</table>

The commented block above creates a binding scope similar to the one on TBODY but without the need for a containing element.

This code snippet should do the trick:

<table>
    <thead>
        <tr>
            <th>Customer Name</th>
        </tr>
    </thead>
    <tbody data-bind="foreach: CustomerArray">
       <!-- ko foreach: Orders -->
       <tr>
            <td data-bind="text: Name"></td>
        </tr>
       <!-- /ko -->
        <tr>
            <td data-bind="text: Name"></td>
        </tr>

    </tbody>
</table>

Hope this solution works for you.
