+
+### tabulate
+
+If you decorate a check method with `tabulate`, information about test case distribution is collected into a table.
+
+The arguments to `tabulate` are the table's name and a _list_ of values associated with the current check. An example:
+
+    /**
+     * @tabulate "Values" [$value]
+     */
+    public function checkBooleans(bool $value)
+    {
+        return true;
+    }
+
+If you run this check, everything passes and a table is output at the end of the check run:
+
+    Tables
+
+    1) Datashaman\PHPCheck\Checks\GeneratorCheck::checkBooleans
+
+    Values (100 total)
+
+       52% true
+       48% false
+
+We'd like to check that the coverage is correct for the generator, so we use a `@coverTable` method annotation:
+
+    /**
+     * @coverTable "Values" [[true, 49], [false, 49]]
+     * @tabulate "Values" [$value]
+     */
+    public function checkBooleans(bool $value)
+    {
+        return true;
+    }
+
+The arguments to the annotation are the name of the table, and a list of key value pairs where the value is the expected percentage distribution.
+
+Here's a sample output from the above:
+
+    1) Datashaman\PHPCheck\Checks\GeneratorCheck::checkBooleans
+
+    Values (100 total)
+
+    54% true
+    46% false
+
+    Table 'Values' had only 46.0% false, but expected 49.0%
+
+We are now warned when the distribution does not fall within the accepted percentage of generated values.
+
+In this case, we would benefit from running the checks a lot more times so we approach the expected _50/50_ average for a boolean:
+
+    /**
+     * @coverTable "Values" [[true, 49], [false, 49]]
+     * @maxSuccess 10000
+     * @tabulate "Values" [$value]
+     */
+    public function checkBooleans(bool $value)
+    {
+        return true;
+    }
+
+Now with _10000_ successful iterations, the warning disappears from the output and the percentage is within the acceptable _1%_ margin of error:
+
+    1) Datashaman\PHPCheck\Checks\GeneratorCheck::checkBooleans
+
+    Values (10000 total)
+
+        50.5% true
+        49.5% false
