If the table is square you might have glass cut to protect it.

You could no doubt pay a carpenter to make this for you for a couple of hundred pound plus materials. Oil it yourself to save more cost, plus it's easy to do.

We all need to eat, but that doesn't mean we can't do it in style! Tell us, what kind of dining room table do you have?

In a lot of cases, I suspect the answer would be for the same reason you do eat at a table - it's what people generally grew up doing, it's what they're used to doing and, being part of the television generation, it's just too convenient to do otherwise. Ironically, I don't tend to watch very much television at all, except when I'm sat, tray in lap, eating ... Another possibility is that not everyone has the space for a permanent formal dining table, and use one with fold-down leaves, for example, which can be hidden away behind an armchair, or somesuch, and wheeled out requiring the moving of other furniture) for special occasions - entertaining, or xmas dinner. For my own part, it's a combination of familiarity, and the fact that it's simply more comfortable to sit in an armchair, or on a sofa, tray on lap, even if I don't bother putting the television on.
