Thanks for the suggestion. How it'll help me to recreate the table? We can't assume blank spaces as a mean to separate cells. I think, we have to add tags between cells while removing the lines. It would be better if we can add <tr>, <td> tags, but any special character to identify the cells would do. A lines removed image won't help us to identify or recreate the data as a table. Sorry if I'm being stupid, but I'm really new to this.
