Saving data in a table field in a matrix field via entry form

Question

I have an entry form with both table fields and matrix fields containing table fields. I can save data into the table fields OK with fields[fieldHandle][X][colX] but with the below, I get a matrix block with the first row in the table field created, but no data in the table field's columns:

<input
    type="hidden"
    value="new:1"
    name="fields[fieldHandle][sortOrder][]"
>
<input
    type="hidden"
    value="blockHandle"
    name="fields[fieldHandle][blocks][new:1][type]"
>
<input
    type="text"
    name="'fields[fieldHandle][tableFieldHandle][X][colX]'"
>

What should it be?

Answer 1

The easiest way to figure this out is to edit an entry with these fields in the CP and monitor the network request that is made on save (or when saving a draft). Here's what I see in my browser dev tools, for example.

Where:

• Matrix field handle = contentBuilder
• Table field handle = tableField

So your fields should be set up as follows (in Craft 4).

fields[matrixFieldHandle][blocks][new1][type] = tableFieldHandle
fields[matrixFieldHandle][blocks][new1][enabled] = 1
fields[matrixFieldHandle][blocks][new1][tableFieldHandle][0][col1] = value1
fields[matrixFieldHandle][blocks][new1][tableFieldHandle][0][col2] = value2
fields[matrixFieldHandle][blocks][new1][tableFieldHandle][0][col3] = value3
