Buttons colvis columns visibility and grouping

eduhutten

In the ColVis Retired version I used the same button to view the columns and grouping. How to rewrite the code with Buttons colvis. Can someone help me ?

colVis: {
exclude: [1,2,3,4],
groups: [
{
title: "Propts. vencer",
columns: [1,2,3,4]
}
]
},
"aoColumns": [
null,

        { "bVisible": false },
        { "bVisible": false },
        { "bVisible": false },
        { "bVisible": false },

        { "bVisible": false },
        null,   
        null,
        { "bVisible": false },  
        { "bVisible": false },  
        { "bVisible": false },
        { "bVisible": false },  
        { "bVisible": false },  
        { "bVisible": false },
        null,
        null,
        { "bVisible": false },
        { "bVisible": false },      
        null,
        null,
        null,
        { "bVisible": false },
        { "bVisible": false }
    ]
