I have a new module created by me.

Here, I've followed this tutorial:

https://devdocs.magento.com/guides/v2.4/ext-best-practices/tutorials/dynamic-row-system-config.html

In this table, I want a column that indicates the row number. How can I do this?

Following Changes you can do
In Step 2, near line no 24 - Ranges.php

protected function _prepareToRender()
    {
        $this->addColumn('S_no', ['label' => __('S_no'), 'class' => 'required-entry']);
        $this->addColumn('from_qty', ['label' => __('From'), 'class' => 'required-entry']);
        $this->addColumn('to_qty', ['label' => __('To'), 'class' => 'required-entry']);

Edit Removed step 4 changes as it is optional step.

  • It will work for the first 2 rows, but I would like the number to be auto-incremented for every row in case I'm adding a new one.

  • Do you create config.xml by yourself or it is autocreated.. , if yourself you can extend it anynumber of times and increament the S_no manually as you are providing details for from_qty and to_qty also and if from_qty and to_qty is also going autometically and config.xml is created autometically then we need to find out which file is creating config.xml file. and we need to add some code there.

  • It can't be manually added, think about 200 entries, I just can't add 200 lines in the config.xml

  • Hey, you are right Step 4 is optional step, So no need to touch the config.xml file(that file is for showing pre-filled rows , actually we don't need any modification there). But what changes we did in Step 2 means we will get the textbox to enter the S_no(not optional) and we can enter S_no while entering the other entities like from_qty. Is it working fine from the browser side ?
