 <el-table
                ref="filterTable"
                :data="tableData"
                :header-cell-style="rowClass"
                :cell-style="set_cell_style"

                style="width: 100%">

rowClass(){
           return 'background:#E6F1FF;color:#368CFF;font-size:13px'
        },
        set_cell_style({ row, column, rowIndex, columnIndex }) {
          // console.log(row, column, rowIndex, columnIndex,"row");
          if (columnIndex === 0) {
              return "background: rgb(230, 241, 255);color: rgb(54, 140, 255)";
            }
        },
