DT 0.4: Editing Tables, Smart Filtering, and More

This article is originally published at https://blog.rstudio.com/

It has been more than two years since we announced the initial version of the DT package. Today we want to highlight a few significant changes and new features in the recent releases v0.3 and v0.4. The full changes can be found in the release notes.

Editable tables

Now you can make a table editable through the new argument datatable(..., editable = TRUE). Then you will be able to edit a cell by double-clicking on it. This feature works in both client-side and server-side (Shiny) processing modes. See here for examples.

Smart filtering in the server-side processing mode

Searching in the server-side processing mode has enabled the “smart” mode by default. Previously, this mode only works in the client-side processing mode. If you want to disable the smart filtering, you can set the initialization option in datatable() (e.g., options = list(search = list(smart = FALSE))). The smart filtering means spaces in the global search keyword for the table will have a special meaning: each returned record in the table should match all of the words separated by spaces. For example, a keyword “1234 abc” will match every record in the table that contain both “1234” and “abc” (in previous versions, this is just treated as a single keyword).

Shift + Clicking for row selection

After you have enabled row selection, you can hold the Shift key and click to select multiple consecutive rows.

DTOutput() and renderDT() for Shiny apps

We have added functions DTOutput() and renderDT() as aliases of dataTableOutput() and renderDataTable(), respectively. This is because the latter two often collide with functions of the same names in shiny. You are recommended to use DTOutput() and renderDT() in Shiny apps, so that you don’t have to worry about forgetting the DT:: qualifier (e.g., DT::renderDataTable). Naming is hard, and this was perhaps my biggest mistake in the initial version of DT. I was too optimistic that DT::renderDataTable() could quickly and easily replace shiny::renderDataTable() so we could drop the latter. It turned out that the two were not completely compatible initially, and had got more and more differences later (DT has many more features).

Versions 0.3 and 0.4 also include several bug fixes, and we appreciate all the bug reports and pull requests from DT users. In particular, we want to thank Xianying Tan (@shrektan) for his many helpful pull requests to implement new features and fix bugs.
