Jinja {{loop.index}} in Alphabet

Frappe Framework Print Formats

Good Day All

I’m trying to make an HTML child table in Print Format, and I’m facing trouble with the {{loop.index}}
In the HTML, the result is a normal serialized numbers.

{%- for row in doc.child_table -%}
<table width=100% border="1">
	<tr>
		<td>Sr.</td>
        <td>Name</td>
	</tr>
    <tr>
    	<td>{{loop.index}}</td>
        <td>{{ row.test_name }}</td>
    </tr>
</table>

Example:

html3
html31546×249 10.3 KB

How can I change the numbers into Alphabet letters ?
Example:

html43
html43934×142 4.87 KB

Thank you :slight_smile:

@Mohd_RTC21 you can do

{%- for row in doc.child_table -%}
<table width=100% border="1">
	<tr>
	    <td>Sr.</td>
            <td>Name</td>
	</tr>
    <tr>
    	<td>{{   chr( (64 + loop.index) % 90 )  }}</td>
        <td>{{ row.test_name }}</td>
    </tr>
</table>
{%- endfor -%}
