redux react-virtualized table x-scrolling

是否可以在react-virtualized中设置x-scrolling?我有一个固定宽度的表格,要显示的列数超过了我表格中的空间,所以我需要一个x-scrollinig。在我的测试中,如果我这样做了,表格只是缩小,如果表格空间不足,只显示'...'的内容。

我自己也为此挣扎了一段时间,我通过将表的宽度设置为width={Object.keys(rows[0]).length*150},并将每个列的最小宽度设置为150(或者无论你选择什么,只要确保它在你的表中是相同的)。
然后将其包在纸中,并给予宽度和溢出X:'auto'
就像这样:

const VirtualizedTable = withStyles(styles)(MuiVirtualizedTable);

export default function DataPreview(props) {

const rows =  [{ One: 'one', Two: 'Two',Three: 'Three',Four:'Four', Five:'Five', Six:'Six'}]

return (
    <Paper style={{ height: 400, width:700, overflowX: 'auto'}}>
        <VirtualizedTable

         width={Object.keys(rows[0]).length*150}
        
            rowCount={rows.length}
            rowGetter={({ index }) => rows[index]}
            
            columns={Object.keys(rows[0]).map(head=>{return(
                {
                    minWidth:150,
                    label:head,
                    dataKey:head
                }
            )})}
        />
    </Paper>
 );
}

react-virtualized Table docs的介绍段落(强调部分已添加):
具有固定标题和窗口行的表组件,用于提高大型数据集的性能。此组件需要显式的widthheight参数。Table内容可以垂直滚动,但不意味着水平滚动。
你也许可以破解它,但它不支持水平滚动,所以它可能不会工作。如果这是你的应用程序的要求,请考虑使用GridMultiGrid

bvaughn的公认答案的基础上,水平滚动表的破解可能看起来像this,但是,要注意这个破解带来的以下警告:

  • 您溢出的Table列将被虚拟化
  • 滚动焦点被 Package 器的x轴滚动捕获,您需要在内部Table组件中单击以重新聚焦并重新获得y轴滚动。这是令人难以置信的令人沮丧的使用,特别是在移动的设备上。

我得到了这样的虚拟化水平滚动:

基本上,添加这3个CSS属性并根据父宽度设置一个显式宽度。It works
