Here I need to increase the width of 2nd and 3rd column ie Name and User

Answer 1

You should set the width of the columns. And you can do that by applying them to the table object. For example:

float[] widths = new float[] { 1f, 2f }; //relative col widths in proportions - 1/3 and 2/3
table.SetWidths(widths);
