グリッド:カスタムセル結合

デフォルトでは、FlexGridはコンテンツに基づいてセルに結合を適用します。

場合によっては、異なる方法でセルを結合することができます。これを実現するには、wijmo.grid.MergeManagerクラスを拡張して、そのオブジェクトを定義してグリッドのmergeManagerプロパティに割り当てます。

import 'bootstrap.css'; import '@grapecity/wijmo.styles/wijmo.css'; import './styles.css'; import * as wjGrid from '@grapecity/wijmo.grid'; import * as wjCore from '@grapecity/wijmo'; export class CustomMergeManager extends wjGrid.MergeManager { constructor(flexGrid) { super(flexGrid); } getMergedRange(panel, r, c, clip = true) { // create basic cell range var rg = new wjGrid.CellRange(r, c); // expand left/right for (var i = rg.col; i < panel.columns.length - 1; i++) { if (panel.getCellData(rg.row, i, true) != panel.getCellData(rg.row, i + 1, true)) break; rg.col2 = i + 1; } for (var i = rg.col; i > 0; i--) { if (panel.getCellData(rg.row, i, true) != panel.getCellData(rg.row, i - 1, true)) break; rg.col = i - 1; } // expand up/down for (var i = rg.row; i < panel.rows.length - 1; i++) { if (panel.getCellData(i, rg.col, true) != panel.getCellData(i + 1, rg.col, true)) break; rg.row2 = i + 1; } for (var i = rg.row; i > 0; i--) { if (panel.getCellData(i, rg.col, true) != panel.getCellData(i - 1, rg.col, true)) break; rg.row = i - 1; } // done return rg; } } function setData(p, r, cells) { if (p.cellType == wjGrid.CellType.Cell) { p.grid.rowHeaders.setCellData(r, 0, cells[0]); } for (var i = 1; i < cells.length; i++) { p.setCellData(r, i - 1, cells[i]); } } function centerCell(s, e) { if (e.cell.children.length == 0) { e.cell.innerHTML = '<div>' + e.cell.innerHTML + '</div>'; wjCore.setCss(e.cell, { display: 'table', tableLayout: 'fixed' }); wjCore.setCss(e.cell.children[0], { display: 'table-cell', textAlign: 'center', verticalAlign: 'middle' }); } } // document.readyState === 'complete' ? init() : window.onload = init; // function init() { // create an unbound grid with 5 rows and 7 columns var theGrid = new wjGrid.FlexGrid('#theGrid'); while (theGrid.columns.length < 7) { theGrid.columns.push(new wjGrid.Column()); } while (theGrid.rows.length < 5) { theGrid.rows.push(new wjGrid.Row()); } // configure the grid theGrid.mergeManager = new CustomMergeManager(theGrid); theGrid.formatItem.addHandler(centerCell); theGrid.rowHeaders.columns[0].width = 80; theGrid.rows.defaultSize = 40; theGrid.alternatingRowStep = 0; theGrid.isReadOnly = true; // populate the grid setData(theGrid.columnHeaders, 0, ',月,火,水,木,金,土,日'.split(',')); setData(theGrid.cells, 0, '12:00,昼のニュース,昼のニュース,昼のニュース,スポーツ,天気予報,未定,未定'.split(',')); setData(theGrid.cells, 1, '13:00,ワイドショー,ワイドショー,アニメ,サッカー,経済ニュース,未定,未定'.split(',')); setData(theGrid.cells, 2, '14:00,ワイドショー,ワイドショー,アニメ,サッカー,ドラマ,未定,未定'.split(',')); setData(theGrid.cells, 3, '15:00,ニュース,ニュース,ニュース,ニュース,ニュース,未定,未定'.split(',')); setData(theGrid.cells, 4, '16:00,ニュース,ニュース,ニュース,ニュース,ニュース,未定,未定'.split(',')); }
