Scalable Column Width in Excel Worksheets

Depiction of data through HTML page is very common, however this page can be opened in variety of devices including mobiles, tabs and other hand held devices which contain small screens. The size of the columns is defined in “pt” which works in many cases. However there can be case where this fixed size may not be required. For example if container panel width is 600px where this HTML page is being displayed. In this case you may get horizontal scrollbar if the generated table width is bigger. This requirement is addressed by providing scalable units like em or percent for a better presentation.

For a working example refer to the following article:

Handle Self-Closing Tags in HTML

Empty tags are very common while working with HTML like we can face <td></td> or simply <td/>. Earlier self-closing tags were not supported however now this support is provided. Now you can load any HTML with self-closing tags and convert it to Excel file.
