Format Markdown tables so that they are readable by humans

[PaulRBerg]

What feature would you like to see?

Markdown tables generated by Codex are not readable by humans - their whitespaces are off.

Not just this but even text outputs, it almost feels like codex is afraid of spacing

I agree that human-readable tables are preferable for terminal output.

However, for repository files, diff-friendly formatting is usually better.
If columns are realigned, even a single change can rewrite the entire table, causing noisy diffs and breaking git blame.
Minimal spacing keeps the change to one line.

So repository files should stay diff-friendly, and only CLI/terminal output should be human-readable.

Human-friendly (aligned columns)

Good for terminal output.
But a small change rewrites the whole table, and git blame becomes unreliable.

| cat     | sun    | red    |
| dog     | sky    | blue   |
| fox     | sea    | green  |

Diff-friendly

Minimal diffs. Git-friendly. git blame remains accurate.
Better for repository files.

| cat | sun | red |
| dog | sky | blue |
| fox | sea | green |

Maybe Codex can generate diff-friendly tables but use a Markdown renderer to display the table in the chat?
