jEditable combined with data tables: Too much whitespace on the editable field

jEditable combined with data tables: Too much whitespace on the editable field

I'm using jEditable in combination with Data Tables plugin to make some columns of the table editable, there is one problem though (not a big one).

When I click on the column which is editable, and suppose it already contains an existing value (for example, a number), it becomes editable but I see that the whitespace between the existing number and the editable text is a lot. So everytime I have to press backspace to go back to the number to edit it. See the attached image for an example.

Does anyone know why is this the case? I'm using the type "text" for that editable column.
