rows().invalidate()
› Invalidate the data held in DataTables for the selected rowsDataTables holds cached information about the contents of each cell in the table to increase performance of table operations such as ordering and searching. If you were to modify the contents of a cell (for DOM data source tables) or the array / object values (for Ajax / JS source tables) DataTables wouldn't know that this has happened. This method can be used to tell DataTables to re-read the information from the data source for the row (be it from the DOM or objects / arrays - whatever the original data source was). This provides an alternative to using row().data() and cell().data() when changing cell values. Typically the data methods are preferred over the invalidation methods, as they use less code, but where the invalidation methods really shine is when the data source for the table are external objects which can be updated using that objects own methods.stateRestoreConfig

Examples
- SearchPanes › Deleting rows mid-searchThis is the searchPanes extension for DataTables. It allows results to be filtered based on the values of columns. searchPanes can be refreshed when data is changed in the table. To demonstrate this, try some of the following. First select 'A' in the pane then play around with the following. Press this button to delete the first row and run the rebuild method on both of the panes: Delete and Rebuild
- Scroller › Client-side data source (50,000 rows)This example is completely artificial in that the data generated is created on the client-side by just looping around a Javascript array and then passing that to DataTables. However, it does show that DataTables and Scroller can easily cope with large amounts of data on the client-side. Typically, data such as this would be Ajax sourced and server-side processing would be implemented. Please be aware that because of the data generation, the performance of this page will depend on your browser - for example IE6 will crawl!
- Responsive › Disable child rowsBy default, when Responsive collapses a table, it will show an option for the end user to expand the row, showing the details of the hidden columns in a child row. This can be disabled using the
responsive.details
option and setting it tofalse
, as shown in the example below. In this case the hidden data is not directly accessible to the end user. - Buttons › Complex table headers - all header rowsThis example demonstrates the use of
colspan
androwspan
in a DataTable and its effect on the exported data. The export formats all allow for column and row spanning elements in the table header. In the case of copy and CSV export an empty string is used, since they are plain text formats and have no concept forcolspan
/rowspan
