This is not really an answer but a large comment that could point out several pitfalls that could have brought you to this point. I am not sure of the best advice for your situation as the warping looks significant. Like discussed in comments I think you might be better off starting over and paying attention to points below.
Knots and Pith
Depending on where you sourced these it is likely that you could have large amount of knots and pith. When you got to purchase lumber you need to check for these things as they will largely affect the drying process.
Why should I avoid using the pith section of quarter sawn lumber?
The wood you purchased should sit in the environment you plan on keeping it in for several weeks or months depending. While it might not looked warped in the store you sometimes don't know how long its been there and more importantly I doubt your build location has the exact same humidity. While gluing can help discourage some movement the wood is still going to lose / gain moisture.
While I would still try this, and look forward to this summer, many would caution against using softwoods like pine, spruce and fir as they can be prone to warping. Also, depending on the use for the table softwood would damage more easily. This point might not be for you but you are likely using pine.
How can I deal with wood from DIY stores that is crooked and may or may not be dry?
The Glue up Process
It is of immense importance that the gluing surfaces are perfectly parallel and flat. A failing in this area would give the wood more room to move as well. Your choice of clamping tools and process would also impact this.
What is a good method for laminating pallet wood/reclaimed lumber?
Alternate Grain During Lamination
When you are gluing up it is important to try and have the grain directions of the boards compliment each other so that when they do try to warp that the other boards will help mitigate the movement. A decent example is on the end of this table:

There are impressive answers using laminating that might be of interest to you that cover these topics in more detail. I added some question links above to some of those questions.
If you do choose to start over and have access to a table saw (With a good outfeed table) you could rip down the table on the glue lines. That could be hard on the blade and hard to do depending on the size of table.
That won't do anything for the warp but what you can do to address that but save the wood is make some cross cuts on the warped boards. Putting them back together will reduce the overall warp of the boards.
Again keeping in mind all of the other point I made above this would be overkill for big box store lumber. It is a solution nonetheless.
