【问题描述】：

我正在尝试为我的表格添加宽度，但由于某种原因我得到以下错误：

问题行

widths: ['auto', 'auto', 'auto', 'auto'],

我的文档定义

var docDefinition = 
        content: [
            text: 'Section A: Facilities and Ambience', style: 'sectionStyling',
            
                style: 'tableExample',
                table: 
                    widths: ['auto', 'auto', 'auto', 'auto'],
                    body: [
                        ['col1', 'col2', 'col3', 'col4', 'col5'],
                        ['some text', '1', '1', '100%', '-'],
                        ['some text', '1', '1', '100%', '-'],
                        ['some text', '1', '1', '100%', '-'],
                        ['some text', '1', '1', '100%', '-'],
                        ['some text', '1', '1', '100%', '-'],
                        ['some text', '1', '1', '100%', '-'],
                        ['some text', '1', '1', '100%', '-'],
                        ['some text', '1', '1', '100%', '-']
                    ]
                
            
        ],
        background: function () 
            return [
                
                    image: 'watermark',
                    width: 200,
                    alignment : 'center',
                    margin: [0, 325, 0, 0]
                
            ];
        ,
        images: 
            watermark: 'data:image/base64....'
        ,
        styles: 
            sectionStyling: 
                fontSize: 18,
                color: 'blue',
                bold: true,
                alignment: 'right',
                margin: [0, 190, 0, 80]
            ,
            subheader: 
                fontSize: 14
            ,
            superMargin: 
                margin: [20, 0, 40, 0],
                fontSize: 15
            
        ,
        defaultStyle: 
            alignment: 'justify'
        
    ;

我试过了（以下都没有）：

widths: ['auto', 'auto', 'auto', 'auto'],
widths: ['auto', 'auto', 'auto'],
widths: [100, '*', 200, '*'],


It works if I just remove the widths line.

【参考方案1】：

您有五列，但只设置了四个宽度。尝试为所有这些设置宽度：

widths: ['auto', 'auto', 'auto', 'auto', 'auto'];

【讨论】：

哦，好吧，我想到了css的宽度。让我测试一下

如果这不起作用，请尝试在宽度数组中添加五个 width: 'auto' 对象
