Add more guides to the docs

[pupudu]

It would be cool if we can add more guides to the guide list in the docs. Currently, there's only the striped-rows guide. From an initial thought, here are some potential guides we can add:

• [ ] Using Custom Components
• [ ] Using Custom Components by Cells (Based on cell data)
• [ ] Fixed/explicit row height
• [ ] Row height based on sampleRowIndex and sampleData
• [ ] Change row height based on index
