This article demonstrates how to insert a nested table in a table cell using Spire.Doc for Java.
import com.spire.doc.*; public class CreateNestedTable { public static void main(String[] args) { //Create a Document object Document doc = new Document(); //Add a section Section section = doc.addSection(); //Add a table Table table = section.addTable(true); table.resetCells(2, 3); //Set column width table.getRows().get(0).getCells().get(0).setWidth(50f); table.getRows().get(0).getCells().get(2).setWidth(50f); table.getRows().get(1).getCells().get(0).setWidth(50f); table.getRows().get(1).getCells().get(2).setWidth(50f); table.autoFit(AutoFitBehaviorType.Auto_Fit_To_Window); //Insert content to cells table.get(0,0).addParagraph().appendText("SI.No."); String text = "Earthwork excavation for foundation of buildings, water supply, " + "sanitary lines and electrical conduits either in pits or in " + "trenches 1.5m and above in width, in ordinary soil not exceeding " + "1.5m in depth including dressing the bottom and sides of pits and " + "trenches, stacking the excavated soil clear."; table.get(0,1).addParagraph().appendText(text); table.get(0,2).addParagraph().appendText("Qty"); //Add a nested table to cell(0,1) Table nestedTable = table.get(0,1).addTable(); nestedTable.resetCells(3, 4); nestedTable.autoFit(AutoFitBehaviorType.Auto_Fit_To_Contents); //Add content to the cells of nested table nestedTable.get(0,0).addParagraph().appendText("SI.No."); nestedTable.get(0,1).addParagraph().appendText("Item"); nestedTable.get(0,2).addParagraph().appendText("Qty"); nestedTable.get(0,3).addParagraph().appendText("Rate"); nestedTable.get(1,0).addParagraph().appendText("1"); nestedTable.get(1,1).addParagraph().appendText("Sand"); nestedTable.get(1,2).addParagraph().appendText("30"); nestedTable.get(1,3).addParagraph().appendText("45"); nestedTable.get(2,0).addParagraph().appendText("2"); nestedTable.get(2,1).addParagraph().appendText("Cement"); nestedTable.get(2,2).addParagraph().appendText("30"); nestedTable.get(2,3).addParagraph().appendText("50"); //Save the document doc.saveToFile("NestedTable.docx", FileFormat.Docx_2013); } }
