Hi,

Column headers in the grid are resizable by default. If you are unable to resize the column headers, then you must have turned this functionality off. Typically, this would be done using the AllowColSizing property.

I don't know what you mean by "left aligned." Column Headers are aligned to the left side of the grid by default. Are you referring to the text inside the column header? I beleive this is also left-aligned by default.
