Auto resize flexgrid column widths
Automatically resize the columns in any flex grid to give a nice, professional appearance. Public sub automatically resizes MS Flex Grid columns to match the width of the text, no matter the size of the grid or the number of columns. Reads first n number of rows of data, and adjusts column size to match the widest cell of text. Will even expand columns proportionately if they aren't wide enough to fill out the entire width of the grid. Configurable constraints allow you to designate 1) Any flex grid to resize 2) Maximum column width 3) the maximum number of rows in depth to look for the widest cell of text.
