我的列宽有问题。我事先不知道它们的宽度，也不想指定每列的宽度。是否有我可以使用的属性根据内容（包括列标题）自动调整所有列宽？

哇！我想出了一个很酷的答案！将宽度设置"auto"为真的不适合我。也许是因为我使用的是ng-view? 没有把握。因此，我创建了 2 个新功能，您可以将其放入controller.js. 像这样使用它们会给你计算出的列宽！阅读代码注释；有一些警告。

示例用法，controllers.js：

var colDefs = makeColDefs(rows[0]);
colDefs = autoColWidth(colDefs, rows[0]);

$scope.phones = rows;
$scope.gridOptions = {
    data : 'phones',
    showFilter : true,
    enableColumnResize : true,
    columnDefs : colDefs
};

代码，controllers.js：

/**
 * Create a colDefs array for use with ng-grid "gridOptions". Pass in an object
 * which is a single row of your data!
 */
function makeColDefs(row) {
    var colDefs = [];
    for ( var colName in row) {
        colDefs.push({
            'field' : colName
        });
    }
    return colDefs;
}

/**
 * Return a colDefs array for use with ng-grid "gridOptions". Work around for
 * "auto" width not working in ng-grid. colDefs array will have percentage
 * widths added. Pass in an object which is a single row of your data! This
 * function does not do typeface width! Use a fixed width font. Pass in an
 * existing colDefs array and widths will be added!
 */
function autoColWidth(colDefs, row) {
    var totalChars = 0;
    for ( var colName in row) {
        // Convert numbers to strings here so length will work.
        totalChars += (new String(row[colName])).length;
    }
    colDefs.forEach(function(colDef) {
        var numChars = (new String(row[colDef.field])).length;
        colDef.width = (numChars / totalChars * 100) + "%";
    });
    return colDefs;
}

Jasmine 测试，controllerSpec.js：

'use strict';

var ROW = {
    'col1' : 'a',
    'col2' : 2,
    'col3' : 'cat'
};
var COLUMN_DEF = [ {
    field : 'col1'
}, {
    field : 'col2'
}, {
    field : 'col3'
} ];
var COLUMN_DEF2 = [ {
    field : 'col1',
    width : '20%'
}, {
    field : 'col2',
    width : '20%'
}, {
    field : 'col3',
    width : '60%'
} ];

/* jasmine specs for controllers go here */

describe('controllers', function() {
    beforeEach(module('myApp.controllers'));

    it('should make an ng-grid columnDef array from a row of data.',
            function() {
                expect(makeColDefs(ROW)).toEqual(COLUMN_DEF);
            });

    it('should return an ng-grid columnDef array with widths!', function() {
        var colDefs = makeColDefs(ROW);
        expect(autoColWidth(colDefs, ROW)).toEqual(COLUMN_DEF2);
    });

});

使用 ui-grid，必须更好：http ://ui-grid.info/docs/#/tutorial/204_column_resizing

但是https://github.com/angular-ui/ng-grid/wiki/Configuration-Options

这有效：

$scope.gridOptions = {
                init: function (gridCtrl, gridScope) {
                    gridScope.$on('ngGridEventData', function () {
                        $timeout(function () {
                            angular.forEach(gridScope.columns, function (col) {
                                gridCtrl.resizeOnData(col);
                            });
                        });
                    });
                },
                data: 'scopeDataField',
                columnDefs: [
                    {
                        field: 'property1',
                        displayName: 'property1title',
                        width: '100px' // a random fixed size, doesn't work without this
                    },
                    {
                        field: 'property2',
                        displayName: 'property2title',
                        width: '100px'
                    }

                ],
                enableColumnResize : true
            };

请参阅https://stackoverflow.com/a/32605748/1688306上的答案

按列名或基准计算的列宽，以较长者为准。

是的！您columndefs可以将宽度设置为auto，这将根据数据和/或标题的宽度自动调整列的大小。

参考：定义列

我正在使用 ui-grid。以下代码对我有用。你可以试试这个。

First you need to add a module dependency 'ui.grid.autoResize' in your main module.

Then add css class something like this 

.grid {
  width    : 400px !important;
  max-width : 400px !important;
  height   : 600px !important;
}

最后像这样在你的 html 文件中添加 ui-grid 指令。请记住，不要忘记ui-grid-auto-resize在您的网格指令中添加“”。

<div id="grid1" ui-grid="gridOptions" class="grid" ui-grid-auto-resize></div>
