@Kiwiwings:
Now I have modified your code to make similar on what I did in actual
project.
Here is the whole demo code:
import java.awt.Color;
import java.awt.geom.Rectangle2D;
import java.io.FileOutputStream;
import java.util.Collections;
import java.util.List;
import java.util.stream.Collectors;
import org.apache.poi.sl.draw.DrawTableShape;
import org.apache.poi.sl.usermodel.TextShape;
import org.apache.poi.xslf.usermodel.XMLSlideShow;
import org.apache.poi.xslf.usermodel.XSLFSlide;
import org.apache.poi.xslf.usermodel.XSLFTable;
import org.apache.poi.xslf.usermodel.XSLFTableCell;
import org.apache.poi.xslf.usermodel.XSLFTableRow;
import org.apache.poi.xslf.usermodel.XSLFTextRun;
public class TableResizeDemo {
public static void main(String[] args) throws Exception {
String[][] data = {
{ "ID", "Name", "Description", "Price",
"Percent", "Current Value" },
{ "123", "Car", "It is new car in 2019",
"$40000", "88%", "$38000" },
{ "123", "Car", "It is new car in 2019",
"$40000", "88%", "$38000" },
{ "123", "Car", "It is new car in 2019",
"$40000", "88%", "$38000" },
{ "123", "Car", "It is new car in 2019",
"$40000", "88%", "$38000" }
};
try (XMLSlideShow ppt = new XMLSlideShow()) {
XSLFSlide slide = ppt.createSlide();
Rectangle2D nextAnchor = displayTable(slide, data,
null);//First
displayTable(slide, data, nextAnchor);//Second
try (FileOutputStream fos = new
FileOutputStream("output/tableTest.pptx")) {
ppt.write(fos);
}
}
}
static Rectangle2D displayTable(XSLFSlide slide, String[][] data,
Rectangle2D nextAnchor) {
XSLFTable tab = slide.createTable(data.length, data[0].length);
for (int row = 0; row < data.length; row++) {
for (int col = 0; col < data[row].length; col++) {
XSLFTableCell c = tab.getCell(row, col);
c.setText(data[row][col]);
c.setTextAutofit(TextShape.TextAutofit.SHAPE);
XSLFTextRun tr =
c.getTextParagraphs().get(0).getTextRuns().get(0);
double fontSize = (0 == row) ? 20. : 15.;
tr.setFontSize(fontSize);
}
}
tab.setColumnWidth(0, 120);//FIXME - issue?
tab.setColumnWidth(1, 120);//FIXME - issue?
// Calculate Gap between tables
Rectangle2D rect = (null != nextAnchor) ?
getGapAnchor(nextAnchor, 20) :
new Rectangle2D.Double(40, 40, tab.getAnchor().getWidth(),
tab.getAnchor().getHeight());
tab.setAnchor(rect);
// Calculate Table's height
calculateTableHeight(tab, tab.getAnchor());
// Get Next Anchor
Rectangle2D anchor = getNextAnchor(tab.getAnchor());
DrawTableShape dts = new DrawTableShape(tab);
dts.setOutsideBorders(Color.DARK_GRAY, 1.0);
return anchor;
}
static void calculateTableHeight(XSLFTable tab, Rectangle2D anchor)
{//FIXME - issue?
double totalCellAnchorHeight = 0;
for (XSLFTableRow row : tab.getRows()) {
/*for (XSLFTableCell cell : row.getCells()) {
cell.resizeToFitText(); //make Cell Height fits
with Text Height
}*/
List<Double> cellAnchorHeightList =
row.getCells().stream().map(c ->
c.getAnchor().getHeight()).collect(Collectors.toList());
double maxCellAnchorHeight =
Collections.max(cellAnchorHeightList);// Get
only Max Cell Anchor's height
totalCellAnchorHeight += maxCellAnchorHeight;
}
Rectangle2D newAnchor = new Rectangle2D.Double(anchor.getX(),
anchor.getY(), anchor.getWidth(), totalCellAnchorHeight);
tab.setAnchor(newAnchor);
}
static Rectangle2D getNextAnchor(Rectangle2D anchor) {//FIXME - issue?
return new Rectangle2D.Double(anchor.getX(), anchor.getMaxY(),
anchor.getWidth(), anchor.getHeight());
}
static Rectangle2D getGapAnchor(Rectangle2D anchor, int gap) {//FIXME -
issue?
return new Rectangle2D.Double(anchor.getX(), anchor.getY() +
gap,
anchor.getWidth(), anchor.getHeight());
}
}
When you run that program, you will see two issues as I wrote:
1. Display text does not fit with column.
For example, less text should display in small column. long text should
display in big column.
2. Calculate table's height, so I can display two or more tables in the same
slide.
I mean after display one table and then need to display second table.
It seems work well with static data but when I applied real data, it does
not work well.
