+The Datasette table view takes a number of special querystring arguments.
+
+Column filter arguments
+~~~~~~~~~~~~~~~~~~~~~~~
+
+You can filter the data returned by the table based on column values using a querystring argument.
+
+``?column__exact=value`` or ``?_column=value``
+    Returns rows where the specified column exactly matches the value.
+
+``?column__not=value``
+    Returns rows where the column does not match the value.
+
+``?column__contains=value``
+    Rows where the string column contains the specified value (``column like "%value%"`` in SQL).
+
+``?column__endswith=value``
+    Rows where the string column ends with the specified value (``column like "%value"`` in SQL).
+
+``?column__startswith=value``
+    Rows where the string column starts with the specified value (``column like "value%"`` in SQL).
+
+``?column__gt=value``
+    Rows which are greater than the specified value.
+
+``?column__gte=value``
+    Rows which are greater than or equal to the specified value.
+
+``?column__lt=value``
+    Rows which are less than the specified value.
+
+``?column__lte=value``
+    Rows which are less than or equal to the specified value.
+
+``?column__like=value``
+    Match rows with a LIKE clause, case insensitive and with ``%`` as the wildcard character.
+
+``?column__glob=value``
+    Similar to LIKE but uses Unix wildcard syntax and is case sensitive.
+
+``?column__arraycontains=value``
+    Works against columns that contain JSON arrays - matches if any of the values in that array match.
+
+    This is only available if the ``json1`` SQLite extension is enabled.
+
+``?column__isnull=1``
+    Matches rows where the column is null.
+
+``?column__notnull=1``
+    Matches rows where the column is not null.
+
+``?column__isblank=1``
+    Matches rows where the column is blank, meaning null or the empty string.
+
+``?column__notblank=1``
+    Matches rows where the column is not blank.
+
+Special table arguments
+~~~~~~~~~~~~~~~~~~~~~~~
 
 ``?_labels=on/off``
     Expand foreign key references for every possible column. See below.
