WiceGrid is a Rails plugin which does all dummy work for you when you need to render a table with:

• paging
• sortable columns
• filtering by multiple columns
• CSV export
• saving queries (considered experimental as of version 0.3)

Filters are added automatically according to the type of the underlying DB column, or can be customized. Filtering by more than one column at the same time is possible. More than one such grid can appear on a page, and manipulations with one grid do not have any impact on the other.
