tables样式和的filter使用咨询

1、用table 绑定了数据后自动生成了一个filter。同时样式也会变化，设置sheet默认的全局样式无效。
  有没有直接设置整个全局的样式，比如字体，背景色 border,而不用一个个单元格设置。
let table = sheet.tables.add("Table1", 0, 0, 1, headers.length);
table.bindColumns(tableColInfos);//绑定table.
sheet.setDefaultStyle(defaultStyle); 没有效果

2.如果添加一列怎么filter也跟着变化，下面代码不生效。如果用sheet.rowFilter就可以。


const range = new GC.Spread.Sheets.Range(startRow,  startCol, rowCount, colCount);
  const rowFilter = new GC.Spread.Sheets.Filter.HideRowFilter(range);
  sheet.tables.findByName('Table1').rowFilter(rowFilter);//不生效
  sheet.rowFilter(rowFilter) //有效

3 怎么获取了filter的contidtion后。然后修改contidtion属性设置进去。是不是获取
filterItemMap 然后设置filterItemMap

您好！关于您关心的问题，解答如下：

问题1：通过Worksheet:setDefaultStyle()可以对整张sheet设置统一的样式，如下动图所示。


也可以通过CellRange:setStyle()对指定区域设置统一的样式。

问题2：Table:rowFilter()用以获取Table的筛选器对象，不能通过该接口设置Table的筛选器，如下图所示。


问题3：可以通过HideRowFilter:addFilterItem()为指定列增加筛选项，将需要筛选的条件封装为Condition对象。
如果需要清除列上原有的筛选条件，可以通过HideRowFilter:removeFilterItems()实现。

    1、
let table=sheet.tables.findByName('Table1');
     let rowFilter=table.rowFilter();
    let condition = new GC.Spread.Sheets.ConditionalFormatting.Condition(GC.Spread.Sheets.ConditionalFormatting.ConditionType.textCondition);
     table.rowFilter().addFilterItem(lastCol,condition)
这样试过不行应该是table没有加入一列，
table.insertColumns(3, 1);这样也能加一列如果要table加一列怎么加。



2、sheet.rowFilter  toJSON 是空
sheet.rowFilter(rowFilter);

var rowFilter = sheet.rowFilter(); //这个能取到值
sheet.rowFilter().toJSON()//这个是空

3 想直接table 的rowFilter.fromJSON 或者sheet.rowFilter().fromJSON(filterJson)这样是否支持。

let filterJson=filter.toJSON();
        let filterItemMap=JSON.parse(filterStr);
        filterJson.filterItemMap=filterItemMap;
        table.rowFilter().fromJSON(filterJson);


4.设置了 sheet.setDefaultStyle(defaultStyle)下面还是在这样是不是要设置table的样式。

1、
let table=sheet.tables.findByName('Table1');
     let rowFilter=table.rowFilter();

1. 如果需要对Table新增行列，是需要通过Table:insertRows()和Table:insertColumns()分别添加行和列，新增的列自动附带有筛选器。HideRowFilter:addFilterItems()只能对Table中存在的列有效。

2. 经测试，未能复现问题，如下图所示。不确定是否是版本之间的差异，我在最新的17.1.8版本测试，需要确认下您使用的是哪个版本？


3. 在HideRowFilter中公开了fromJSON()和toJSON()，即可支持筛选器对象的序列化。

4. 结合您前后提供的信息，需要确认下您是否想要添加的Table的样式与Worksheet一样呢？由于插入Table时会产生默认的Table样式，如果不需要，可以清除Table的样式，参考如下代码：

1. sheet.tables.remove('TableName', GC.Spread.Sheets.Tables.TableRmoveOptions.keepData);

复制代码

可以参考官网API文档了解详情：
TableManager:remove()--https://demo.grapecity.com.cn/spreadjs/help/api/classes/GC.Spread.Sheets.Tables.TableManager#remove
TableRemoveOptions--https://demo.grapecity.com.cn/spreadjs/help/api/enums/GC.Spread.Sheets.Tables.TableRemoveOptions

设置 table的filter 。然后sheet的rowFilter没有设置。用这个代码table.rowFilter().fromJSON(filterJson);  
fromJSON下面的代码怎么不生效，也就是不会有过滤。

设置一个这样的filterjson字符串的代码
  let filterJson=JSON.parse(filterStr);
  // filterJson.filterItemMap=filterItemMap;
   table.rowFilter().fromJSON(filterJson);

设置 table的filter 。然后sheet的rowFilter没有设置。用这个代码table.rowFilter().fromJSON(filterJson); ...

一般情况下，通过HideRowFilter:fromJSON()成功反序列化筛选器对象后即已生效，由于此时未对Table执行筛选，因此无法看到筛选条件的生效结果，需要对筛选器执行filter()方法才能令序列化数据中的筛选条件生效。如下动图所示：
