One approach would be place the entire table within a container that fits on the page. Style it to have hidden overflow so the extra table content is hidden. Include nav buttons that when clicked, invoke a JS function to alter the table’s “left” style value in a way that exposes the next several columns within the container. This means negative left values so the table’s actual edge is well off to the left somewhere outside of the viewport.
How easy this is to accomplish depends on how well you work with JS and CSS.
As you’ve noticed by now, these forums are not a good venue if you are really in a hurry. If time is that important, consider hiring a developer who would be more responsive to your needs. We are happy to help you when we can, but such help can be slow in coming.
It nice to see your response and your tip are very valuable for me. Can you please refer me to any good course of WordPress developing for fast learning from beginning to advance.
I’m sorry but I don’t know anything specifically that I could recommend. IMO, training courses are good for a general overview of what the possibilities are, but one doesn’t typically learn practical skills that way. Practical skills are acquired by working on real world projects. That takes time. Everyone learns new skills differently. Maybe a few can quickly absorb all the training and be able to expertly apply it to new projects, but I think they are quite rare. Most people need to repeatedly practice something before it really becomes a skill. Only time will let you do that.
You should by all means seek out and complete good online training courses. But don’t expect that alone to make you an advanced developer. I applaud your desire to learn and hope it serves you well. If you’re one of those rare few maybe it will come quickly.
