You can easily remove any row that you selected, only question is if
you can select apropriate rows.
$("table tr").remove(".remove"); // removes any table rows that
have class="remove"
or like this
$("table tr").filter(":contains(unwantedText)").remove(); //
removes any row containing string "unwantedText"
Only thing you have to watch is that your query is TR element (that
was your problem, right?).
If you filter by some other condition, for example children elements,
then do this:
$("table tr a.remove").parent().remove(); // query is A tag with
class="remove", so you escape it with .parent()
Same thing goes with adding rows, just use .after("<tr>Insert this
row</tr>") or .before("<tr>Insert this row</tr>") methods.
