The bug
Markdown rendering of tables does not handle right-justification.
':' characters in the header line dashes should apply left/right/center justification of the header text and column content.
|-----| no justification
|:----| left justification
|----:| right justification
|:----:| center justification
You can reproduce this by running the logmerger logmerger --demo command, and open the "info" dialog.
Here is a sample markdown table with justification settings:
| Dependency | Version | Center | Left | Right |
|-------------|-------|:------:|:-----|------:|
| textual | 6.4.0 |Y| xyz | 123 |
| littletable | 3.0.2 |N| abc | def |
