Markdown tables have strange column widths #6252
Description
While trying to investigate #6239, I found that the column widths in Markdown tables might be a bit strange.
For example, here's a simple markdown table where all the cells are identical:
from textual.app import App, ComposeResult
from textual.widgets import Markdown
LONG_TEXT = "Lorem ipsum dolor sit amet"
MARKDOWN = f"""
| Header 1 | Header 2 | Header 3 | Header 4 |
|-------------|------------ |-------------|-------------|
| {LONG_TEXT} | {LONG_TEXT} | {LONG_TEXT} | {LONG_TEXT} |
"""
class ExampleApp(App):
CSS = """
Markdown { max-width: 88; }
"""
def compose(self) -> ComposeResult:
yield Markdown(MARKDOWN)
if __name__ == "__main__":
app = ExampleApp()
app.run()I
