Update: bug fix for column format changes via adding rows in the API

Previously, if you used the API to add rows to an empty or small table, a column format may have changed based on an inference of the values passed in your request. This was unintended and some users who encountered it may have suppressed it manually using the disableParsing URL parameter (which is related but designed for a slightly different use case). We will deploy a fix on Tuesday, September 21, 2021 to fix this so that adding rows via the API never changes a column format.
