The Table Grid Editor is a JIRA add-on that allows you to store tabular data in the context of an issue.
It is available in Atlassian Marketplace.
It is possible to synchronize the data contained in such grids between the two instances by using the Table Grid API in the Incoming sync.
The following script example shows how this can be done.
