Setting column width in angular ui grid

If you are looking for fixed width, you can use the width property in the colomnDefs like this:

columnDefs : [
            { field : 'pageIcon', displayName : 'Page Icon', width : 25},
            { field : 'pageName', displayName : 'Page Name', width : 100},
            { field : 'count',    displayName : 'Count',     width : '30%'}
]

After you have set your column definitions, you can add the following

for (var i = 0; i < $scope.gridOptions.columnDefs.length; i++) {
    $scope.gridOptions.columnDefs[i].width = '10%';
}

This will set all of the columns to the width you select. With 30 columns at 10% the user will use the horizontal scrollbar to see all the columns, as you prefer. I didn't change any CSS.

The best way is to use the GridOptions minimumColumnSize property:

$scope.gridOptions.minimumColumnSize = 100;

Zero performance impact and no oddities with the CSS methods.

Reference page, Ctrl-F minimumColumnSize: http://ui-grid.info/docs/#!/api/ui.grid.class:GridOptions

Try by the following function by calling before ui-grid data source binds.

 function SetColumnWidth() {
        var cols = _.filter($scope.gridOptions.columnDefs, function (c) {
            return c.visible != false;
        });
        var maxWidth = (document.documentElement.clientWidth) / cols.length;
        for (var i = 0; i < cols.length; i++) {
            cols[i].maxWidth = parseInt(maxWidth);
        }
    }

set column width to width: "*" and set minWidth as per convinient.

This solution is work for any screen as, especially large resolution screen. It will manage to equally divide maxWidth of all columns and cover the whole area of the screen.

you can add a style to your css

.ui-grid-header-cell {

    min-width: 200px !important;
    max-width: 300px !important;

}

If you will add width using for loop or like ways it may slow down rendering of your grid, So I would suggest to do it via CSS. Because I had same problem with 15,000 rows and 80 columns and I tried adding width using loop and it seems to slow down rendering of grid. So, Try adding below code in your CSS, it will solve your purpose.

.ui-grid-header-cell {
 min-width: 200px !important;
 max-width: 300px !important;
}

.ui-grid-cell {
min-width: 200px !important;
max-width: 300px !important;
}
