+## Parameters
+

+A predicate function for matching keys in a table's group key.
+`tableFind` returns the first table that resolves as `true`.
+It expects a `key` argument which represents a group key in the input stream.
+
+_**Data type:** Function_
+
+##### Example fn function
+```js

+ |> filter(fn:(r) => r._measurement == "cpu")

+// t represents the first table in a stream whose group key
+// contains "_field" with a value of "usage_idle".
+```
