how does the key in the columns1 item above relate to the key in the data below
for example: the first key in columns1: "name" can be associated with the name:" John Brown" in the data below, and will be displayed in a column in table. I want to encapsulate a component similar to this table, which can achieve the simplest data presentation, but I don"t understand how the js of this component is implemented

The problem that

wants to solve is (above)
the student name of the object passed in cannot correspond to the gray header (student name)
the effect above is directly misplaced

how to make it the same as the table of iview, no matter what order the objects are passed in the background, they can correspond to each other in table

culumns generates column data, first of all, headers. We don't talk about multiple headers here, but we need to add additional attributes. The th in the header is generated according to the culumns loop. If it is useless, it is the title attribute in it.

followed by the body, tr is generated according to the data loop, and the td is generated according to the culumns loop. The content is the data in the data, that is,

data[i][culumns[j].key]

actually requires only a simple list. The order of names is determined according to the location of the array, and then rendered to the list. You can also add custom instructions to add class or other

instructions.
