Hi,

I am new to Ruby on rails and facing trouble in setting the column width of the table.

I am generating a word document (RoR app) where I have multiple tables and I use "com.lowagie.text.Table".

However, I am not able to change the width of the table column.

Need some more details. According to your question I think you have to set the column length through model.

Let's say we have a model called customer.rb
and we have a column name "first_name" and we have to set its maximum length to 30 characters.

If the length exceed 30 characters then a error message should be shown.
So we have to do like this-

C#

validates :first_name, presence: { message: 'Please enter your First Name.'}
validates :first_name, :length => { :maximum => 30, :message => 'Please enter a First Name of 30 characters or less in length.' }

Hope this will help!! :)
