Install the plugin using the Universal Plugin Manager
Check out the documentation on the atlassian site how
to add a plugin. Search for the table grid plugin, and press the install button or download it directly from the plugin exchange.
Security aspect
Grids created with the plugin might be vulnerable for XSS attacks. When using these grids in a security sensitive environment (such when accessible through the internet),
make sure to use gd.enableXSSValidation property. This will disable any script code which might be injected into the grid cells. If in doubt - please contact us.
Backup of table grid data
As JIRA administrator you must be aware that the data stored in the grid table is NOT included in the xml backup.
The reason is that the grid table can be stored in any database, and not necessary in the JIRA database.
Secondly, even Atlassian is indicating that for production systems, you should rely on the native database backup tools instead of JIRA's
XML backup service. Check document here.
Please be sure that your disaster recovery procedure is thoroughly tested and includes the table grid data. In case of doubt, check with your Atlassian Solution Partner, or contact us.
