• Performance
• Fully compatiable with bootstrap 3 and 4(react-bootstrap-table@4.0.0 already done)
• Clean Code and Testing
• Decrease the size of bundled file
• Split module/functionality from core module, make core module more lightweight
• Use storybook to build examples
• Support the aggregation(summary) view
• Support the table footer
• Support column/row span on header and body
• Support sticky header
• Support table section(react-bootstrap-table#721)
• Handle events well
• Fix unalign issues
• Make stateless table more easy to use(react-bootstrap-table alread have remote mode but have some bugs)
• Customizable table
• Support the nested data(react-bootstrap-table#50)
• Consider to support column resize
• Consider to make animation on react-bootstrap-table2 more easy

• Have a great chance that I don't support the vertical scrollbar on table
