I want all rows disable so the user can't click on any column unless the row is selected.

I don't think you can do that from within the framework. Apex mediates all DA events, and I don't find any Apex equivalent to `preventDefault` or `stopPropagation`. You'll have to add your own DOM event handler. Define a DOM `clilck` handler to the Page `Function and Global Variable Declaration`

var selectedOnly = false;

function clickCatcher (browserEvent) {
    if (!window.selectedOnly) return;

    var tr = browserEvent.target.closest('tr');
    if (tr && !tr.classList.contains('is-selected')) {
      browserEvent.stopPropagation();
    }
};

attach an event listener in `Execute when Page Loads`

document.getElementById('my_ig')
        .addEventListener('click', clickCatcher, true);
//document.getElementById('my_ig').removeEventListener('click', clickCatcher, true);

and set `window.selectedOnly` to true when you want to block clicks on rows that are not selected.

Now some bad news: (1) In 19.1 you'll still lose the selection when you cllck on a selected row. (2) You can still navigate to an unselected row using the keyboard. (We're only blocking clicks here.)

You can disable all columns through a "Selection Change" dynamic action. And that's after checking that there are more than one row checked using getSelectedRecords() api and "length" array property.
