This article is about how layui implements merging cells in dynamic tables. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Demand:

The following excel table is used to roughly simulate the requirements. The left side is the original, and it should be changed to something like this on the right:

Step 1 of ①: call this method after generating the table to merge duplicate cells

Done: function (res, curr, count) {merge (res);}

Step 2 of ②: write this method:

Function merge (res) {var data = res.data; var mergeIndex = 0 id','name' / locate the number of rows that need to add merge attributes var mark = 1; / / A simple operation is involved here. Mark is to calculate the number of cells that need to be merged each time. Var columsIndex = [010] / / column index value for (var k = 0; k) to be merged

.layui-table ") .find (" tr "); / / all rows for (var I = 1; I < res.data.length; iTunes +) {/ / the current data of the circular table here var tdCurArr = trArr.eq (I). Find (" td ") .eq (columsIndex [k]) / / get the current column of the current row var tdPreArr = trArr.eq (mergeIndex) .find ("td") .eq (columsIndex [k]) / / get the first column if of the same column (data [I] [columsname [k] = = data [I-1] [columsname [k]]) {/ / the value of the latter row is compared with that of the previous row, and the same requires merging mark + = 1 TdPreArr.each (function () {/ / the first column of the same column adds the rowspan attribute $(this) .attr ("rowspan", mark);}) TdCurArr.each (function () {/ / current line hidden $(this) .css ("display", "none");});} else {mergeIndex = I; mark = 1 / / once the values of the front and back lines are different, then the number of cells to be merged mark needs to be recalculated}} mergeIndex = 0; mark = 1;} thank you for reading!
