The page introduces how to create multi-header which has multiple rows as the header of a table.
A header cell in a table indicates the meaning or purpose of the whole column. When the table needs more than one rows as the header for special purpose (as the following figure), users can create multi-header. Usually in this scenario, you need to merge some header cells, such columnA and columnB. This is also included in this task.
1 Specify the value for headerRows in Properties section.
As shown below, the value is 2.
2 Add the columns.
Each cell in multi-header takes for one column. Thus, there is 7 columns.
3 Select the 'browse' button beside the text field. In the pop-up windows, set the title name, header level, and span.
Notes
▪ Text: Column 0 and 1 are named columnA and columnB; Column 2, 3, 4, 5, and 6 are named column0, column1, column2, column3, and column4.
▪ Header level: Column 0 and 1 are in level 1( Row 1); Column 2, 3, 4, 5, and 6 are in level 2 (Row 2).
