Free Text column value with Kendo Grid Column

Hello Hitesh,

Straight to your questions: 

    1. There is a restriction only that columns.field should  be a valid Javascript identifier and should contain no spaces, no special characters, and the first character should be a letter.

     2. There is a style applied to the td elements  (using the .k-grid td selector) with line-height: 1.6em; If you use higher specificity you can apply your own line height value in order to override the default one.
