I am increasing the width of a single cell in a table (w:tc/w:tcPr/w:tcW/w:w = "5000") through .NET code

This works, but the rest of the cells are increasing automatically.

To do this manually I would just highlight the cell and drag the border to the desired length. But through code I cannot highlight the cell, so all other cells with align automatically.

Is there a property to change this?

Thanks,Mc
