How to delete a column header?

[hugoliang]

Dear All,

I have a question about table.

The output of column header property is an array of string. At first, it has two elements, but after edit the third column, it will have three elements.
When deleted all character of the third column, the output of the property has three elements(the third element is empty).
How to delete a column header to let the property has two elements?

Thanks.

Hi,

I think the easiest way is to use property node once:

don't know how to remove empty elementh in the header in Edit Mode.
