Bring the power of Handsontable to Python and Jupyter Notebook

Project description

pyhandsontable

Build Status PyPI version shields.io PyPI license PyPI pyversions

View a 2-D array, probably from pyexcel in Jupyter Notebook, and export to *.html.

Installation

pip install pyhandsontable

Usage

>>> from pyhandsontable import view_table
>>> view_table(width=800, height=500, data=data_matrix, **kwargs)
A Handsontable is shown in Jupyter Notebook.

Acceptable kwargs

  • title: title of the HTML file
  • maxColWidth: maximum column width. (Default: 200)
  • renderers: the renderers to use in generating the columns (see below.)
  • autodelete: whether the temporary HTML file should be autodeleted. (Default: True)
  • filename: filename of the temporary HTML file (default: 'temp.handsontable.html')
  • css: url of the Handsontable CSS
  • js: url of the Handsontable Javascript
  • config: add additional config as defined in https://docs.handsontable.com/pro/5.0.0/tutorial-introduction.html
    • This will override the default config (per key basis) which are:
{
  data: data
  rowHeaders: true,
  colHeaders: true,
  dropdownMenu: true,
  filters: true,
  modifyColWidth: function(width, col){
    if(width > maxColWidth) return maxColWidth;
  }
}

renderers example, if your data is a 2-D array:

{
    1: 'html',
    2: 'html'
}

or if your data is list of dict:

{
    "front": 'html',
    "back": 'html'
}

Post-creation editing of the HTML

You might try from bs4 import BeautifulSoup:

    renderers = {
        1: 'markdownRenderer',
        2: 'markdownRenderer'
    }
    config = {
        'colHeaders': ['id'] + list(CardTuple._fields),
        'rowHeaders': False
    }

    filename = 'temp.handsontable.html'
    try:
        table = view_table(data=([[i] + list(record.to_formatted_tuple())
                                  for i, record in self.find(keyword_regex, tags)]),
                           width=width,
                           height=height,
                           renderers=renderers,
                           config=config,
                           filename=filename,
                           autodelete=False)
        with open(filename, 'r') as f:
            soup = BeautifulSoup(f.read(), 'html5lib')

        div = soup.new_tag('div')

        js_markdown = soup.new_tag('script',
                                   src='https://cdn.rawgit.com/showdownjs/showdown/1.8.6/dist/showdown.min.js')
        js_custom = soup.new_tag('script')

        with open('gflashcards/js/markdown-hot.js') as f:
            js_custom.append(f.read())

        div.append(js_markdown)
        div.append(js_custom)

        script_tag = soup.find('script')
        soup.body.insert(soup.body.contents.index(script_tag) + 1, div)

        with open(filename, 'w') as f:
            f.write(str(soup))

        return table
    finally:
        Timer(5, os.unlink, args=[filename]).start()
