The height of the bootstrape Table control is set, and the header is not aligned after the width of each column

After the height of the bootstrape table control is set, the header is easily confused. The fundamental reason is that we add the table-Layout:fixed property to the table of the content, but the header does not have this property, so we also add table-Layout to the table of the header. :fixed attribute is enough (for single-line header tables)
