Table span problem

Hi I am having one problem with cell span in a table:

I define next table declaration:

[cols="2*", options="header"]
.Properties
|===

|KEY
|VALUE

|key
|value

|key2
|value2

2x|somePath

|===

Basically what I want is span to the end the last row so it fills both columns. For this reason I have added the 2x. The problem is that it doesn't span the row, but the first cell is empty and the second one contains 2x.

Also is there any way to avoid that Asciidoctor doesn't add the "Table1", "Table2", ... label on a labeled table?

Thank you so much.

Resolved, I have written 2x instead of 2+ which is the correct option.
