Datatable: How to change minimum width of the cell in table

I want to change minimum width of cell in the data table.
Rest I want to confirm about the default functionality that all the cells width are set according to longest value in the cell… Is this correct ?

You can use minColumnWidth option

and adjustColumn to fit column size to content ( it will be limited by minColumnWidth value )
