Do the <th scope="row"></th> cell always must be in the first column?
I have a table that have the most important field in the second column, so I do not know if I can place the scope attribute in another column.
<table> <tr> <td>Data</td> <th scope="row">Most Important Data</th> <td>Data</td> <td>Data</td> </tr> </table>

Yes the scope refers to an entire row or column in a table, so this would need to be the first "cell" in your row. Remember in a table, a column is made up of one or many rows. :-)
<table> <tr> <th>Title</th> <th>Second Title</th> </tr> <tr> <td> </td> <td> </td> </tr> <tr> <td> </td> <td> </td> </tr> <tr> <td> </td> <td> </td> </tr>
No, the scope does not need to be the first "cell". For example, U can have the following code; which is perfectly valid HTML:
<table> <tr> <th scope="col">Number</th> <th scope="col">Name</th> <th scope="col">Job</th> </tr> <tr> <td>1.</td> <th scope="row">John Doe</th> <td>Sales Manager</td> </tr> <tr> <td>2.</td> <th scope="row">Jane Doe</th> <td>CEO</td> </tr> </table>

I think the importance of the
scope attribute when used within a row is to identify the key column. If you relate this to how databases are used, you usually have a key column. The values in this column should be always unique when compared against the other rows in the same column. This works like an
id that can be related to the information on other cells of the same row.
In conclusion, within a row, you can use any of the cells as your key, as long as you always use the same cell position for all rows.
