[JAVA] Create PDF with itext7-Free layout: Table-

Let's arrange the table freely

This time, the table is freely arranged. In the previous Paragraph, the position was slightly off, so I think it is one way to arrange the character strings in a table with one cell.

Description

The position specification is the same as last time. In order to make the width easy to understand, I made a step in every 100.

Output image

Export is specified position + specified height.

The table is also displayed from the height above the specified position in the same way as the character string. There seems to be no gap in the table.

The excess is output at the same position on the next page.

The lines that also stick out are displayed on the next page. However, the header footer seems to be displayed on each page.

Specify column width

Table table = new Table (new float [] {100,200,300}); indicates that 3 columns are specified and the ratio of each width is 100: 200: 300. The specified width is 400, but the width is set as a percentage regardless of this. However, for some reason, the new float [] {1,2,3} has the same width (it seems that the old version was made?), And the new float [] {10,20,30} causes an error. It is had. why. For the time being, it seems that it should be specified with a somewhat large value. ,
