Methods

buildCell(row, dom) → {Promise|*}

Description:

  • Builds out the DOM element, typically a td, that represents the
    intersection of this column with a particular row. Often this will simply
    be a simple toString() or similar, but could also do more sophisticated
    things like build widgets.

Source:
Inherited From:
Parameters:
Name Type Description
row module:nmodule/webEditors/rc/wb/table/model/Row
dom JQuery
Returns:

promise to be resolved when the element's contents
have been fully built. It's also acceptable for overrides of this function
to complete synchronously without returning a promise, so be sure to wrap
calls to this function in Promise.resolve() when appropriate.

Type
Promise | *

destroyCell(row, dom) → {Promise|*}

Description:

  • Called when the table is destroying the DOM element built for a cell in this column. This
    gives a Column implementation the chance to clean up any resources that might have been
    created during the earlier call to #buildCell, perhaps destroying a widget in the cell,
    for example. As with #buildCell, if this completes synchronously and doesn't return a
    Promise, the caller must wrap this in a call to Promise.resolve().
