我使用javascript来匹配两个单独表中的列的宽度（使用它来创建一个可滚动的，粘性的头表。如果数据全部可见（没有溢出），该方法工作正常。但是，如果表溢出，但是，表格列没有对齐。我有一个调试流，显示offsetWidths仍然返回相同的数字。有关为什么会发生这种情况的任何想法？

需要修复两个表的表格布局，以便调整单元格的大小并使其作为整体影响表格。默认情况下，这是auto，表格会调整其单元格容器/内容的大小。
这对我在Dart工作，应该适应js
adjustHeaderWidth() {
if ( tableHeader.rows.length < 1 || table.rows.length < 1 )
return;
List hd = tableHeader.rows[0].cells;
List bd = table.rows[0].cells;
if ( hd.length < 1 || bd.length < 1)
return;
num index = 0;
hd.forEach((f) {
var width = math.max(bd[index].client.width, f.client.width);
f.style.width = '${width}px';
bd[index].style.width='${width}px';
index++;
}
);
}
