Currently, DMN Runner uses two tables, one for inputs and the other for outputs. This can cause some inconsistencies and adds complexity to syncing both tables. Changing it to one table would improve UI and UX.
### Acceptance criteria
- [ ] DMN Runner Table should render one table instead of two;
- [ ] The outputs should always be visible, so it requires adding a column freeze functionality in the table.
