    …ividual value, an array or an object as the first parameter passed to it. The individual and array options behave exactly as they did before this change - the new option is the object being passed in. This allows fnupdate to be given a data object which is identical to data objects used by the table when using complex objects and mDataProp. How fnUpdate itself actually operates has also changed to be self calling, which makes the multipe column updates for arrays and objects much easier.
    
    Fix: fnUpdate now works with TH elements in the body as well as TD elements

    …ery start of each table draw (so rather like fnDrawCallback, just before the
    
    draw!). This function is, like all other DataTables callbacks, execuated with the DataTables instance scope, and also takes a single parameter -
    the DataTables settings object. The attached function can cancel the draw by returning false, anyother return (including undefined) results in the
    full draw occuring).

    indication that the data is currently being sourced from the server (i.e. Loading...) rather than showing 'No data available in table' - which is
    not particularly friendly. Note that for server-side processing, DataTables will leave whatever is in TBODY when it makes the first Ajax request,
    so with server-side processing you would need to put in a TR/TD into the static HTML table.

    …to the offset calculation done with the huge flat array of TD nodes. The fix is to simplify this somewhat and get an array for each row (when it is available) and process that using the optional parameter for _fnGetTdNodes. This doesn't result any any extra computation time, other than the addional time to call the function (but not to execute it), since it is just moving where the loop is.

Basically browsers need a bit of a hand when a width is assigned to any columns when x-scrolling as they tend to collapse the table to the min-width, even if we sent the column widths. So we need to keep track of what the table width should be by summing the user given values, and the automatic values

With sContentPadding you can add an extra string to any column to force DataTables to take account of this during the width calculation - the string in sContentPadding is not used anywhere else and is empty by default. This option will remain undocumented for the moment, since I suspect it will confuse more than help, but it is very useful to have around when x-scrolling.

    … we are going to be using strings for the display - so cast as a string, which means that we can take the length of any primitive (particularly numbers).
    
    Fix: The max string width calculation was including HTML, which is just plain wrong since the HTML will be hidden. This is still not perfect since "iiii" takes less space than "mmm" in the browser display, but addressing that would take some serious clocks cycles, and this is good enough for now.

This meant that when the cell was actually created and the data source attempted to be read, the rendered string wasn't available - thus you got an empty cell (4943). This fix is to add a condition to the rendering call to delay until the node is created. Note that there is still a quirk here, in that the rendered data cannot be used for sorting or filtering, since again it isn't stored anywhere when the data source is null.

In addition to this, when set if the mDataProp value is undefined, the default will be used instead (and no error given). If sDefaultContent is not set (default is null), and the mDataProp value is undefined, an error will be given as it currently is.
