Abstract:
The present application relates to a method performed at an electronic device for parsing tables in a PDF document. The method includes the following steps: receiving the PDF document containing a table area; extracting horizontal lines, vertical lines and text blocks in the table area; determining the types of tables in the table area according to the extracted horizontal lines and vertical lines; if the table is a quasi full-line table, determining the structure of the quasi full-line table in the table area according to the horizontal lines and the vertical lines in the table area with the assistance of the text blocks in the table area; and if the table is a quasi non-line table, determining the structure of the quasi non-line table in the table area according to the text blocks in the table area with the assistance of the horizontal lines and/or the vertical lines in the table area.

Claim (Index 17):
The electronic device according to  claim 13 , wherein the step of extracting the horizontal lines and the vertical lines in the table area comprises:\n extracting all path drawing information in a PDF page and merging the same into lines; if the coordinate of a line on they direction is greater than or equal to they coordinate of the upper frame of the table area and is less than or equal to they coordinate of the lower frame of the table area, and the coordinate of a left endpoint on the x direction is greater than or equal to the x coordinate of the left frame of the table area and is less than the x coordinate of the right frame of the table area, and the coordinate of a right endpoint on the x direction is greater than the x coordinate of the left frame of the table area and is less than or equal to the x coordinate of the right frame of the table area, collecting the line as a horizontal line; and if the coordinate of a line on the x direction is greater than or equal to the x coordinate of the left frame of the table area and is less than or equal to the x coordinate of the right frame of the table area, the coordinate of an upper endpoint on the v direction is greater than or equal to the y coordinate of the upper frame of the table area, and the coordinate of a lower endpoint on the y direction is less than or equal to they coordinate of the lower frame of the table area, collecting the line as a vertical line.
