如何设置作为单元格表(GWT)中行和列交叉点的单元格的样式? [英] How to style the cell that is the intersection of row and column in celltable (GWT)?

问题描述

好的，我有一个 CellTable，它有 3 列和 2 行.我希望表格中某些特定单元格(不是所有单元格)中的文本为粗体.

请看这段代码:

ListDataProvider>dataProvider = new ListDataProvider>();dataProvider.addDataDisplay(table);列表<列表<字符串>>list = dataProvider.getList();列表<字符串>sublist1= Arrays.asList("223","546","698");列表<字符串>sublist2= Arrays.asList("123","876","898");列表<字符串>sublist2= Arrays.asList("123","896","438");IndexedColumn column1=new IndexedColumn(0);table.addColumn(column1, "Col1");IndexedColumn column2=new IndexedColumn(1);table.addColumn(column2, "Col2");IndexedColumn column3=new IndexedColumn(2);table.addColumn(column3, "Col3");

我试过了，差不多完成了，但是...

假设我想为以下行索引和列索引的交集的单元格设置样式:(注意:索引从 0 开始，所以 column2 得到索引 = 1)

<前>行 - 列0 - 10 - 21 - 11 - 22 - 2

显然，我只想设置 5 个单元格的样式.

所以我确实像你说的那样:

在 css 文件中:

.boldRow .boldColumn { 字体粗细:粗体；}

然后在java文件中

column2.setCellStyleNames(getView().getRes().css().boldColumn());column3.setCellStyleNames(getView().getRes().css().boldColumn());table.setRowStyles(new RowStyles>() {@覆盖public String getStyleNames(List row, int rowIndex) {if(rowIndex==0 || rowIndex==1 || rowIndex==2){返回 getView().getRes().css().boldRow();}返回空；}});

这是结果:

<前>Col1 - Col2 - Col3223 - 546 - 698123 - 876 - 898123 - 896 - 438

显然，我不希望此单元格(行索引 = 2 & 列索引 = 3)加粗.但结果包括它.

那么如何解决呢?

解决方案

找到我的帖子 如何根据该单元格的值 (GWT) 在 CellTable 中设置特定单元格的样式?.

这将解决您的问题.

在AbstractCell

中使用下面的代码

<代码> ...FontWeight 权重 = FontWeight.BOLD;if (context.getColumn()==0 || (context.getIndex()==1 && context.getColumn()==2)) {重量 = FontWeight.NORMAL;}...

Ok, i have a CellTable that has 3 columns and 2 rows. I want the text in SOME specific cells (not all cell) in the table to be BOLD.

Please look at this code:

ListDataProvider<List<String>> dataProvider = new ListDataProvider<List<String>>();
dataProvider.addDataDisplay(table);
List<List<String>> list = dataProvider.getList();
List<String> sublist1= Arrays.asList("223","546","698");
List<String> sublist2= Arrays.asList("123","876","898");
List<String> sublist2= Arrays.asList("123","896","438");
IndexedColumn column1=new IndexedColumn(0);
table.addColumn(column1, "Col1");
IndexedColumn column2=new IndexedColumn(1);
table.addColumn(column2, "Col2");
IndexedColumn column3=new IndexedColumn(2);
table.addColumn(column3, "Col3");

I tried, it almost done, BUT...

Suppose I want to style the cell that is the intersection of the following Row Index and Column Index: (Note: index start from 0, so column2 got index=1)

Row - Col
0   -  1
0   -  2
1   -  1
1   -  2
2   -  2

Clearly, I just want to style 5 cells only.

So i did like you said:

in css file:

.boldRow .boldColumn { font-weight: bold; }

Then in the java file

column2.setCellStyleNames(getView().getRes().css().boldColumn());
column3.setCellStyleNames(getView().getRes().css().boldColumn());

table.setRowStyles(new RowStyles<List<String>>() {
   @Override
   public String getStyleNames(List<String> row, int rowIndex) {


      if(rowIndex==0 || rowIndex==1 || rowIndex==2){
          return getView().getRes().css().boldRow();
      }
      return null;
   }

});

ANd here is the result:

Col1 - Col2 - Col3
223 - 546 - 698
123 - 876 - 898
123 - 896 - 438

Clearly, i don't want this cell (row index =2 & columm index=3) bold. But the result include it.

So how to fix it?

解决方案

Find my post her How to style specific cells in CellTable depending the value of that cell (GWT)?.

This will solve your problem.

Use below code in AbstractCell

        ...
        FontWeight weight = FontWeight.BOLD;
        if (context.getColumn()==0 || (context.getIndex()==1 && context.getColumn()==2)) {
            weight = FontWeight.NORMAL;
        }
        ...
