html code for rowspan ?

Here is an example of HTML code using the `rowspan` attribute:

```html

Header 1	Header 2	Header 3
Row 1, Cell 1	Row 1, Cell 2	Row 1, Cell 3
	Row 2, Cell 2	Row 2, Cell 3
Row 3, Cell 1	Row 3, Cell 2	Row 3, Cell 3

```

In this example, the `rowspan="2"` attribute is used in the first cell of the first row to span two rows. This means that the cell will take up the space of two rows in the table.

```html

Header 1	Header 2	Header 3
	Data 1	Data 2	Data 3

```
