When I paste an Excel table in Thunderbird e-mail client (ver 24.2.0) the table looses its formatting. One workaround seems to be that you paste the table from Excel to Word and then paste it in Thunderbird. But this seems a bit odd as Word and Excel are part of the same Office Suite of applications, yet their behavior is strange.
Can anybody shed any light on it?
Copy from Excel, Paste into word -> Paste Options -> Keep Source formatting, then highlight the table, Go to Design -> on the right, Increase the "Line Weight" to a minimum of 1 point, then click on "Borders" and select "All Borders"
Now copy this table and paste it in your Email. It should work.
