Don't use links in dynamic block

When creating a dynamic block, the heading column creates a link for each field. I want to disable this behaviour.

```org
| Heading | Scheduled | Deadline |
|--------------------------------------+------------+------------|
| [[Milestone 2][Milestone 2]] | 2023-02-09 | 2023-02-27 |
| [[Milestone 3][Milestone 3]] | 2023-03-03 | 2023-03-13 |
| [[Milestone 4][Milestone 4]] | 2023-03-15 | 2023-04-06 |
| [[Milestone 5][Milestone 5]] | 2023-04-06 | 2023-04-19 |
| [[Testing document][Testing document]] | 2023-02-26 | 2023-02-28 |
| [[Assignment][Assignment]] | 2023-02-15 | 2023-03-01 |
| [[Midterm][Midterm]] | 2023-03-03 | 2023-03-08 |
```

I want it to be like this:

```org
| Heading | Scheduled | Deadline |
|--------------------------------------+------------+------------|
| Milestone 2 | 2023-02-09 | 2023-02-27 |
| Milestone 3 | 2023-03-03 | 2023-03-13 |
| Milestone 4 | 2023-03-15 | 2023-04-06 |
| Milestone 5 | 2023-04-06 | 2023-04-19 |
| Testing Testing document | 2023-02-26 | 2023-02-28 |
| Assignment | 2023-02-15 | 2023-03-01 |
| Midterm | 2023-03-03 | 2023-03-08 |
```

I am using the table with gnuplot, and it breaks the parsing...
