Release DT 0.21 · rstudio/DT

NEW FEATURES

Add the zero.print argument to formatPercentage(), formatCurrency(), formatSignif() and formatRound(), which allows to control the format of zero values. It's useful when the data is "sparse" (thanks, @shrektan #953).
formatXXX() functions now gain a new argument rows (starting from 1), which can be used to specify the rows that the "style" should be applied to. Note that it only works expected in the client-side processing mode, i.e., server = FALSE. formatStyle() is the only exception that doesn't have this argument and should use styleRow() instead (thanks, @jrecasens @shrektan #520).
Added a new function updateFilters to allow users to update the filters of a DataTable object that has been updated by reference, such as with replaceData() (thanks, @giadasp #934, @wholmes105 #939).

Now users can provide column names of the data to options$columnDefs$targets. Previously, it only supports column indexes or "_all" (thanks, @shrektan #948).

styleRow() and styleEqual() now allows a scalar values argument like other R functions, e.g., styleRow(1:5, 'abcd') is the same as styleRow(1:5, rep('abcd', 5)). It throws error that the length(rows) must be equal to length(values) in the previous version (thanks, @shrektan #955).

Fix the bug that addRow() doesn't support a list of data after R 3.4.0, where structure(NULL, ...) was deprecated (thanks, @stla @shrektan #959).
Fix the bug that DT table can't vertically fill the container, e.g., RStudio IDE or FlexDashboard (thanks, @mbojan @shrektan #951).
Fix the bug that DT failed to parse ajax request correctly, when special strings like "=" exist (thanks, @shrektan #965).
