# reactable 0.2.3.9000 Unreleased

This release upgrades to a new major version of React Table (#35), which introduces many new features, improvements, and bug fixes. Backward compatibility was kept where possible, but note that there are several breaking changes.

### New features

• Column group headers can now be resized.
• Column group headers and filters are now sticky. Previously, only column headers were sticky (#107).
• Sticky columns are now supported using a new sticky argument in colDef() and colGroup() (#19, #72, #141).
• Cell content can now be vertically aligned using the new vAlign and headerVAlign arguments in colDef(), and the new headerVAlign argument in colGroup() (#142, #177).
• reactable() gains a paginateSubRows argument to include grouped sub rows in pagination. This is recommended for larger tables with row groups that may not all fit on the page when expanded.
• Expanded rows now stay expanded on sorting, filtering, and pagination changes. Previously, expanded rows were always collapsed on sorting and pagination changes, and incorrectly persisted on filtering changes (#39).
• Aggregated rows can now be selected when multiple selection is enabled.
• colDef() gains a grouped argument to customize rendering for grouped cells in groupBy columns (#33, #94, #148).
• JavaScript render functions and style functions receive several new properties:
• rowInfo.expanded and cellInfo.expanded indicating whether the row is expanded
• cellInfo.selected property indicating whether the cell’s row is selected
• state.page, state.pageSize, and state.pages for the current page index, page size, and number of pages in the table
• JavaScript render functions for cells, headers, footers, and row details can now access the table state using a new state argument (#88).
• Custom cell click actions can now access the table state using a new state argument.
• R render functions for row details now receive an additional argument for the column name (@ksnap28, #155).

### Breaking changes

• The row selection column is now always placed as the first column in the table, even before the groupBy and row details columns (#71).
• Increased the default width of the row selection column to match the row details column (45px).
• When both columnGroups and groupBy arguments are provided, groupBy columns are no longer added to a column group automatically (#87).
• The defaultGroupHeader argument in reactableLang() is now deprecated and no longer used. Use the columnGroups argument in reactable() to customize the column group header for groupBy columns.
• The state.expanded property has been removed from JavaScript render functions and style functions. To check whether a row is expanded, use rowInfo.expanded instead.
• The rowInfo.page and cellInfo.page properties have been removed from JavaScript render functions and style functions. To get the current page index of the table, use state.page instead.

### Minor improvements and bug fixes

• Setting show = FALSE as a default value in defaultColDef() now works (@csgillespie, #105).
• Using a single value for pageSizeOptions in reactable() now works.
• Column resizing is now limited by the min and max width of the column.
• Column group headers and filter cells in fixed height tables now display properly in Safari, Chrome, and the RStudio Viewer (#76).
• In reactable(), defaultExpanded = TRUE now expands all rows in the table, not just rows on the first page.
• In reactable(), defaultExpanded = TRUE now works when column groups are present.
• Aggregated cell values are now recalculated when filtering or searching the table.
• Aggregate functions now always take the unaggregated values in the column. Previously, if there were multiple groupBy columns, aggregate functions could take aggregated values which could produce inaccurate calculations (e.g., when calculating the mean of values).
• The "max" and "min" aggregate functions now work on dates, date-times, and strings (#130).
• Column formatters no longer apply to empty aggregated cell values.
• Searching now properly ignores the row details and selection columns.
• Selected rows now reset when the table data changes in Shiny (#110).
• When selecting rows, errors from other Crosstalk widgets no longer cause the table to disappear.
• HTML widgets and HTML dependencies in nested tables now render correctly (#125).
• Tables are now displayed with full width when rendered inside an R Markdown document or R Notebook (#163).
• reactable() now works for data frames with difftime objects and objects with custom classes (#164).
• colFormat() no longer ignores time zones when formatting dates and times.
• Row expand buttons now set the aria-expanded attribute to indicate expanded or collapsed state. The default label for row expand buttons is now “Toggle details” instead of “Expand details” or “Collapse details”.
• reactableLang() gains the groupExpandLabel and groupCollapseLabel arguments to customize the accessible labels for row group expand buttons.
• Cells in the row names column are now marked up as row headers for assistive technologies.
• The page info and “no rows found” message are now marked as ARIA live regions so that page changes can be announced by assistive technologies when searching, filtering, or paging through the table.
• In reactableTheme(), filterInputStyle now applies correctly when rerendering a table in Shiny (#186).
• In reactableTheme(), cellPadding now applies to column group headers correctly.
• Columns with square brackets ([ or ]) in their column name now render correctly (#187).

• colFormat() now always formats numbers as a localized string when locales is specified.
• Table rows no longer stretch to fill the height of the container (#69). To make rows stretch again, use a theme like reactableTheme(tableBodyStyle = list(flex = "auto")).

• New getReactableState() function to get the state of a reactable instance in Shiny (#20).
• colDef() gains a "median" aggregate function to calculate the median of numbers (#30).
• The row selection column can now be customized using ".selection" as the column name (#19).
• In reactable(), the rowClass, rowStyle, and details JavaScript functions now receive a rowInfo.selected property indicating whether the row is selected (#20).
