Header, Footer in middle. Coloumn/rows lines darker?

Salman,
Yes it’s possible to have one column and text in the middle of the cell. You have two options to do that:
1) Under page setup Footer or Heading change Divide into: ?? Sections to 1. (it will have only one column)
2) Keep the Divide into: 3 Section to three columns but leave the left and right column blank then un-tick show sections divider lines.

To make the lines darker? Unfortunately not possible.

Thanks a lot Mr.Rodel,

Is there any way to view layout header only in the middle of the cell.

Salman,
If you need only Headers only on the middle of the cell then under Footer tab -> Include on: (change to: "No Pages"). For the Headers select any of the options I mentioned to have it on the center.

Once again thanks for your reply,

I am sorry that I could not able to communicate my query properly.

well,The thing which I am looking for is: When we open a project, we have coloumn headers...Activity ID, Activity Name, start, finish... (Time scale Format).........and these are shown on the top left corner of the cell, to take an example, the description of activity Ids are normally lone like " Installation of Pump Foundations", where as its coloumn header "Activity Name" will be shown in top left corner in its cell. Can we make that in middle.

Thanks in advance.

Salman,
For the column Headers, Screen or Print out view - unfortunately not possible.
