The

### Tables
The mentoring table allows you to present answers to multiple
free-form questions in a concise way. The table consists of mulitple
columns defined with the
`<column>`
element. Each
`<column>`
element
should contain a
`<header>`
and an
`<answer>`
element. The
`<header>`
elements sets the text of the header while the
`<answer>`
element
references a free-form question through its mandatory
`name`
attribute.
#### Example
These example shows a table containing to two previously answered
questions.
```
xml
<mentoring
url_name=
"goal_table"
>
<mentoring-table
url_name=
"goal_table"
>
<column>
<header>
Your goal
</header>
<answer
name=
"goal"
/>
</column>
<column>
<header>
Your Other Goal
</header>
<answer
name=
"goal_other"
/>
</column>
</mentoring-table>
</mentoring>
```
free-form questions in a concise way. Once you create an "Answer
Recap Table" inside a Mentoring component in Studio, you will be
able to add columns to the table. Each column has an optional
"Header" setting that you can use to add a header to that column.
Each column can contain one or more "Answer Recap" element, as
well as HTML components.

### Maximum Attempts

setting the
`max_attempts`
