问题描述

我正在使用 SpreadsheetFormatColumns() 将电子表格中的列格式化为文本"，但我不知道该怎么做，livedocs 中的所有格式都是数字、货币或日期...像

I am using SpreadsheetFormatColumns() to format the columns in a spreadsheet to "text", but I don't know how to do this, all the formats in the livedocs are for numbers, currency or dates... is there something like

SpreadsheetFormatColumns(mySpreadsheet, {dataFormat="text"}, "1-15")

SpreadsheetFormatColumns(mySpreadsheet, {dataFormat="text"}, "1-15")

out there? this is really bugging me...

推荐答案

在 ColdFusion 9.0.1(即更新程序 1)中，如果您使用 SpreadsheetSetCellValue() 它将尊重您之前设置的格式.因此，要在填充工作表时强制将列作为文本，您可以使用 3 步过程:

In ColdFusion 9.0.1 (i.e. updater 1), if you use SpreadsheetSetCellValue() it will respect the format you have previously set. So to force a column to be text when populating a sheet you can use a 3-step process:

1. 填充电子表格，忽略错误解释的数字值.
2. 将您想要的列格式化为文本.
3. 用正确的值替换列中每一行中的错误值，该值现在将被视为文本.

这是一个示例，您可以将其复制到 .cfm 中并按原样运行(需要 CF9.0.1)

Here's an example which you can copy into a .cfm and run as-is (requires CF9.0.1)

<cfscript>
    // Create a 2 column, 2 row query. The first column contains numbers or possible numbers we want formatted as text in our spreadsheet
    q   =   QueryNew( "" );
    QueryAddColumn( q,"NumbersAsText","VarChar",[ 01050094071094340000,"743059E6" ] );
    QueryAddColumn( q,"Text","VarChar",[ "abc","def" ] );
    // Get the column names as an array so we can get at them more easily later
    columns =   q.getMetaData().getColumnLabels();
    // Create a new spreadsheet object
    sheet   =   SpreadSheetNew( "test" );
    // specify the column we want formatted as text
    forceTextColumnNumber   =   1;
    // Use the query column names as column headers in our sheet
    SpreadSheetAddRow( sheet,q.columnList );
    // Add the data: the numbers will be inserted as numeric for now
    SpreadSheetAddRows( sheet,q );
    // Now we format the column as text
    SpreadSheetFormatColumn( sheet,{ dataformat="text" },forceTextColumnNumber );
    // Having formatted the column, add the column from our query again so the values correct
    while( q.next() )
    {
        // Skip the header row by adding one
        rownumber   =   ( q.currentrow + 1 );
        // Get the value of column at the current row in the loop
        value   =   q[ columns[ forceTextColumnNumber ] ][ q.currentrow ];
        // replace the previously added numeric value which will now be treated as text
        SpreadsheetSetCellValue( sheet,value,rownumber,forceTextColumnNumber );
    }
    // Download the object as a file
    sheetAsBinary   =   SpreadSheetReadBinary( sheet );
    filename    =   "test.xls";
</cfscript>
<cfheader name="Content-Disposition" value="attachment; filename=#Chr(34)##filename##Chr(34)#">
<cfcontent type="application/msexcel" variable="#sheetAsBinary#" reset="true">

默认情况下，查询的第一列中的两个值都将被视为数字(第二列为十六进制).使用此方法都将其原始值保留为文本.

By default, both of the values in the first column of my query would be treated as numbers (the second as a HEX). Using this method both preserve their original value as text.
