Table column line moves

[joannechee2]

Hi! I've got trouble adjusting the line of my columns.



Previously, the document had separate tables with page breaks. Meaning each page has a table. Then I went to remove all the page breaks and combined all table as one because I want to have header rows. When I did this, the size of the header row is fixed, but, since previously each page had its individual table, the column line could have slightly different widths. They might have been manually adjusted by the previous person since each page had an individual table. Now, when I try to manually adjust the column lines to match the lines of the header row, it will affect the column lines of subsequent parts of the table, because now I'm using Page Break Before instead.

I can't get the column lines to align to the header row without affecting column lines in subsequent pages (Page Break Before applied). Please help, thanks!
