+Most error classes returned by Spark SQL are associated with a 5 character `SQLSTATE`.
+A `SQLSTATE` is a SQL standard encoding for error conditions commonly used by `JDBC`, `ODBC`, and other client APIs.
+
+A `SQLSTATE` consists of two portions: A two character class, and a three character subclass.
+Each character must be a digit `'0'` to `'9'` or `'A'` to `'Z'`.
+
+While many `SQLSTATE` values are prescribed by the SQL standard, others are common in the industry, specific to Spark.
+
+For an ordered list of error classes see: [Error Conditions in Spark SQL](sql-error-conditions.html)
+
+Spark SQL uses the following `SQLSTATE` classes:
+
+## Class `0A`: feature not supported
+
+<table class="table">

Review Comment:
   I am not entirely sure, but it seems like Jekyll(the tool used for building documentation in OSS Spark) has specific rules for conversion. I checked the table may not be built properly if we don't use the html tag here.
