# How To: Number Table Rows
Use the `rownum` keyword when tables need a visible line counter.
### Problem
You want to add row numbers to your related list tables.
### Solution 1: Basic Row Numbers
```
```
**Result:**
```
| # | Product | Price |
|---|---------|--------|
| 1 | Widget | $10.00 |
| 2 | Gadget | $25.00 |
```
### Solution 2: Custom Starting Number
**Start at 10:**
```
rownum
```
**Result:** Numbering starts at `10`.
### Solution 3: Formatted Row Numbers
**Add Prefix and Postfix:**
```
rownum
```
**Result:**
```
| Line | Product | Price |
|---------|---------|--------|
| Item 1: | Widget | $10.00 |
| Item 2: | Gadget | $25.00 |
```
### Tips
* `rownum` is a special keyword, not a field name.
* Numbering starts at `1` by default.
* `startIndex="3"` starts numbering at `4`.
* Combine it with `prefix` and `postfix` for custom labels.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://help.sdocs.com/sdocs/advanced-template-logic/template-attributes/template-attributes-how-to-guides/how-to-number-table-rows.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
