|

<li>type=date, format=yyyy-mm-dd</li>

<p>Following additional instance properties:</p>
|

|

<p>@property {Function} renderer: a function to render the data for this field.
|

Signature: function(value, field, doc) where value is the value of this
|
||||
cell, field is corresponding field object and document is the document
|
||||
object. Note that implementing functions can ignore arguments (e.g.
|
||||
function(value) would be a valid formatter function).</p>
|
||||
|
||||
<p>@property {Function} deriver: a function to derive/compute the value of data
|
||||
in this field as a function of this field's value (if any) and the current
|
||||
document, its signature and behaviour is the same as for renderer. Use of
|
||||
this function allows you to define an entirely new value for data in this
|
||||
field. This provides support for a) 'derived/computed' fields: i.e. fields
|
||||
whose data are functions of the data in other fields b) transforming the
|
||||
value of this field prior to rendering.</p>
