I have an excel spreadsheet with numbers of the form 0.75464, i.e. Zero Point a string of numbers.
I paste this into a Confluence Cloud Table and the cells with these numbers in are transformed into table cells <td>, containing ordered lists <ol> with the fractional part (or mantissa) only of the number appearing as a list item. This is therefore rendering the number with a proceeding 'Item number' which makes it appear as if it is 1.XXXX, e.g. 1. 75464.
This did not happen on local Confluence Server. I have tried formatting the numbers differently in excel but to no avail. I am using MacOS 10. I have tried with the latest Safari and Chrome.
