Allow Table to use finalize_hooks

[jordansamuels]

Currently, it doesn't look like Table and TablePlot are wired to use finalize_hooks. Using them would allow things like wiring HTMLTemplateFormatter for cells. The below is a way to do this without modifying HoloViews, and so the feature would be to incorporate the few lines of wiring into TablePlot instead of overriding here.

from holoviews.plotting.bokeh.tabular import TablePlot
from holoviews.element.tabular import Table
class TableWithHooks(Table):
    pass
class TableWithHooksPlot(TablePlot):
    finalize_hooks = param.HookList(default=[])

    def initialize_plot(self, ranges=None, plot=None, plots=None, source=None):
        super(TableWithHooksPlot, self).initialize_plot(ranges, plot, plots, source)
        self._execute_hooks(self.hmap.last)

    def _execute_hooks(self, element):
        for hook in self.finalize_hooks:
            try:
                hook(self, element)
            except Exception as e:
                self.warning("Plotting hook %r could not be applied:\n\n %s" % (hook, e))
    
hv.Store.register({TableWithHooks: TableWithHooksPlot}, 'bokeh')


name = ['homepage', 'github']
link = ['http://holoviews.org', 'https://github.com/ioam/holoviews']
table = TableWithHooks({'Name':name, 'Link':link},  vdims = ['Name', 'Link'],  kdims=[])

from bokeh.models import HTMLTemplateFormatter
def apply_format(plot, element):
    plot.handles['plot'].columns[1].formatter=HTMLTemplateFormatter(template='<a href="<%= value %>"><%= value %></a>')

table.opts(plot=dict(finalize_hooks=[apply_format]))

Looks like this was merged a while back.
