ng-grid automatically resizing columns based on content width

I am currently utilizing AngularJS ng-grid and endeavoring to accomplish the following tasks: 1. Adjust column width dynamically based on the content within each column. 2. Automatically resize the last column to fill the remaining space when hiding columns (For instance, if there are 8 columns each with a width of 100 and the total ng-grid width is 800...if 4 columns are hidden, the last column should automatically expand to a width of 500).

At present, I have implemented code for task 1 but it's not functioning as expected (columns are not resizing according to the content). Therefore, I'm seeking assistance in identifying any missing elements and guidance on how to achieve task 2. Thank you


var app = angular.module('myNGridApp', ['ngGrid']);

app.controller('myNGCtrl', function($scope) {
    $scope.myData = [{id: "#4", di: 50, taskstatus: "Lorem Ipsum text", notes: "Lorem Ipsum text", datecreated: "02/04/2014"},
                     {id: "#4", di: 50, taskstatus: "Lorem Ipsum text", notes: "Lorem Ipsum text", datecreated: "02/04/2014"},
                     {id: "#4", di: 50, taskstatus: "Lorem Ipsum text", notes: "Lorem Ipsum text", datecreated: "02/04/2014"},
                     {id: "#4", di: 50, taskstatus: "Lorem Ipsum text", notes: "Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text Lorem Ipsum text ", datecreated: "02/04/2014"},
                     {id: "#4", di: 50, taskstatus: "Lorem Ipsum text", notes: "Lorem Ipsum text", datecreated: "02/04/2014"}];

   $scope.columnDefs= [{ field: 'id', displayName: 'ID', resizable: true, minWidth: 100, width: 'auto' },
                         { field: 'di', displayName: 'DI', resizable: true, minWidth: 100, width: 'auto' },
                         { field: 'taskstatus', displayName: 'Task Status', resizable: true, minWidth: 200, width: 'auto' },
                         { field: 'notes', displayName: 'Notes', resizable: true, minWidth: 400, width: 'auto' },
                         { field: 'datecreated', displayName: 'Date Created', resizable: true, minWidth: 200, width: 'auto' }];

      $scope.gridOptions = { 
        data: 'myData',
        columnDefs: 'columnDefs',
        footerVisible: true,
        enableColumnResize: true,
        filterOptions: {filterText: '', useExternalFilter: false},
        showColumnMenu: true,
        showFilter: true,
        plugins: [new ngGridFlexibleHeightPlugin()],
        virtualizationThreshold: 10,
    };

});

Answer №1

After facing the same challenge, I finally found a solution that met my needs. Hopefully, it can benefit someone else as well!

Essentially, I input the first row of data and an optional object containing user-friendly column names. If certain names are not included or if the object is omitted, the script will automatically format the names by splitting camelCase, replacing underscores and hyphens with spaces, and capitalizing the first letter.

The calculation for column width is based on a monospaced font (such as Lucida Console), using the longer of the column name or the data to determine the width.

if(!datum || datum.toString().length < displayName.length)
  result.width = displayName.length * 7.5;
else
  result.width = datum.toString().length * 7.5;

if(result.width < 40)
  result.width = 40;
