Magento2.1.X_AddCompanyColumnToSalesOrderGrid
You can see the company column on sales order grid at backend page like this
Default loading page https://github.com/meezin/Magento2.1.X_AddCompanyColumnToSalesOrderGrid/blob/master/readme/3.png
After clicking the filter https://github.com/meezin/Magento2.1.X_AddCompanyColumnToSalesOrderGrid/blob/master/readme/2.png
- BUG FIX
If you use this module of prior version, filter would be loacted at bottom of page because it comes from how UI components are rendered. Before fixing a bug, the loading time was so slow and filter was located below. But after configuring <listingToolbar name="listing_top"/> above your <columns>tag, it works fine.
