We can use the ``SeparatorFormatParser`` to ignore reading certain lines by using a callback function. We illustrate this using the above data, skipping any rows with ``edge.name`` starting with ``edge``.

>>> tips = LoadTable(filename="t3.tab", reader=reader, digits=1, space=2)

In the above example, the data type in a column is static, e.g. all values in ``x`` are floats. Rather than providing a custom reader, you can get the ``Table`` to construct such a reader based on the first data row using the ``static_column_types`` argument.
