 You can fix the column by setting the Fixed attribute of the column and scroll.x, and fix the header by setting scroll.y.
 
 > -   Make sure that all elements inside the table do not affect the height of the cells after rendering (e.g. containing unloaded pictures, etc.). In this case, give the stator element a definite height to ensure that the left and right Fixed columns of cells are not deranged.
-> -   If the column header is not aligned with the content or there is a column duplication, specify the width width of the fixed column. If the specified width is not effective, try to recommend leaving a column with no width to accommodate the elastic layout, or check for ultra-long continuous fields to destroy the layout.

 > -   It is recommended to specify scroll.x as a **fixed value** or percentage greater than the width of the table. It is recommended to set a fixed value of `>= the sum of all fixed column widths + the sum of all table column widths`.

 可以通过设置 column 的 `fixed` 属性以及 `scroll.x` 来进行列固定，通过设置 `scroll.y` 来进行表头固定。
