I have a beautiful looking html table from jsfiddle which i will love to convert to excel document. My problem is after creating the excel file. The table loses it styles in excel such as font color, padding, background color. etc. is there a fix for this?

HTML

<table id="testTable" summary="Code page support in different versions of MS Windows." rules="groups" frame="hsides" border="2"><caption>CODE-PAGE SUPPORT IN MICROSOFT WINDOWS</caption><colgroup align="center"></colgroup><colgroup align="left"></colgroup><colgroup span="2" align="center"></colgroup><colgroup span="3" align="center"></colgroup><thead valign="top"><tr><th>Code-Page<br>ID</th><th>Name</th><th>ACP</th><th>OEMCP</th><th>Windows<br>NT 3.1</th><th>Windows<br>NT 3.51</th><th>Windows<br>95</th></tr></thead><tbody><tr><td>1200</td><td style="background-color: #00f; color: #fff">Unicode (BMP of ISO/IEC-10646)</td><td></td><td></td><td>X</td><td>X</td><td>*</td></tr><tr><td>1250</td><td style="font-weight: bold">Windows 3.1 Eastern European</td><td>X</td><td></td><td>X</td><td>X</td><td>X</td></tr><tr><td>1251</td><td>Windows 3.1 Cyrillic</td><td>X</td><td></td><td>X</td><td>X</td><td>X</td></tr><tr><td>1252</td><td>Windows 3.1 US (ANSI)</td><td>X</td><td></td><td>X</td><td>X</td><td>X</td></tr><tr><td>1253</td><td>Windows 3.1 Greek</td><td>X</td><td></td><td>X</td><td>X</td><td>X</td></tr><tr><td>1254</td><td>Windows 3.1 Turkish</td><td>X</td><td></td><td>X</td><td>X</td><td>X</td></tr><tr><td>1255</td><td>Hebrew</td><td>X</td><td></td><td></td><td></td><td>X</td></tr><tr><td>1256</td><td>Arabic</td><td>X</td><td></td><td></td><td></td><td>X</td></tr><tr><td>1257</td><td>Baltic</td><td>X</td><td></td><td></td><td></td><td>X</td></tr><tr><td>1361</td><td>Korean (Johab)</td><td>X</td><td></td><td></td><td>**</td><td>X</td></tr></tbody><tbody><tr><td>437</td><td>MS-DOS United States</td><td></td><td>X</td><td>X</td><td>X</td><td>X</td></tr><tr><td>708</td><td>Arabic (ASMO 708)</td><td></td><td>X</td><td></td><td></td><td>X</td></tr><tr><td>709</td><td>Arabic (ASMO 449+, BCON V4)</td><td></td><td>X</td><td></td><td></td><td>X</td></tr><tr><td>710</td><td>Arabic (Transparent Arabic)</td><td></td><td>X</td><td></td><td></td><td>X</td></tr><tr><td>720</td><td>Arabic (Transparent ASMO)</td><td></td><td>X</td><td></td><td></td><td>X</td></tr></tbody></table>

    , base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))) }
    , format = function(s, c) { return s.replace(/{(\w+)}/g, function(m, p) { return c[p]; }) }
  return function(table, name) {
    if (!table.nodeType) table = document.getElementById(table)
    var ctx = {worksheet: name || 'Worksheet', table: table.innerHTML}
    window.location.href = uri + base64(format(template, ctx))

Finally I figured it out. Using an embedded or external CSS style will not work.

Observations

  1. CSS must be inline
  2. CSS must be on th or td elements of the table because they represent cells in Excel
  3. Colors should be hex

Summary

From the above code, I don't need an external CSS style. All my CSS styles need to be inline in the table.
