求问各位大佬，在导入文件的时候跳出来了：
no room to add more variables because of width
    Width refers to the number of bytes required to store a single
    observation; it is the sum of the widths of the individual
    variables.  The maximum width allowed is 1,048,576 bytes.  You
    just attempted to exceed that.
error in line 0 of file

这可咋办呀
