Hopefully this is self-explanatory.. links inside Rich Text in a DataTable appear not to respect link-color, link-background, link-style.... end result being links and non-links are indistinguishable until you trace the mouse over table contents? Here is a simple example. Sorry for formatting, not sure how to upload a code example yet:

from textual.app import App, ComposeResult
from rich.text import Text 
from textual.widgets import Static
from textual.widgets import DataTable

ROWS = [
    ("lane", "swimmer"),
    (4, "Table Text only appears to respect link CSS [@click=app.bell]when you position the mouse over the link itself? i.e. respects link-style-hover, link-color-hover, link-background-hover but not link-color, link-background, link-style[/]"),
]

class TableApp(App):
     CSS = """
    * {
    link-color: blue;
    link-background: purple;
    link-style: underline blink;

    link-style-hover: blink;
    link-color-hover: green;
    link-background-hover: yellow;
    }
"""

    def compose(self) -> ComposeResult:
        yield Static("Regular text respects link css [@click=app.bell]all the time[/]")
        yield DataTable()

    def on_mount(self) -> None:
        table = self.query_one(DataTable)
        table.add_columns(*ROWS[0])
        for row in ROWS[1:]:
            styled_row = [
                Text.from_markup(str(cell), style="italic #03AC13", justify="right") for cell in row
            ]
            table.add_row(*styled_row)

app = TableApp()
if __name__ == "__main__":
    app.run()
